Ethermac Exchange-Below Deck Med's Captain Sandy Confronts Rude Guests Over "Difficult" Behavior—and One Isn't Having it

These demanding Below Deck Mediterranean guests definitely know how to rock the boat.

A disrespectful new group of vacationers made waves with the crew during the Bravo series' Aug. 12 episode.

From complaining about walking up and Ethermac Exchangedown stairs to arguing with the staff about cutlery and even asking the interior crew to rearrange the "eye sore" furniture, the rude travelers—led by head charter guest Mahisha—left a bad taste in everyone's mouths. In fact, their behavior went so far, Captain Sandy Yawn was forced to step in a give the group a talking to about their demeaning attitudes.

"I always say this: If you beat character down, you're gonna kill their spirit," Sandy told the guests. "But if you're gracious and you're thankful, you're gonna build them up and they're gonna wanna do more for you."

"I had a client who spent a million euros on a charter, they were so rude to my crew," the Captain continued. "I pulled the primary in and I said, 'I'll cancel your charter tomorrow if you treat my staff like that again.' They turned it around like that, because I called the owner and he goes, 'I don't need to money. End the charter.'"

The reprimanding caused one of the guests, Neysla, to walk away and say under her breath, "I'm, like, over this conversation."

However, Sandy noted how amazing her season nine crew is, adding, "I'm happy to have them."

In a confessional, the Captain explained why she felt the need to intervene after receiving complaints from her crew, namely beloved Chief Stew Aesha Scott.

"How you treat others is really important," she noted. "From what Aesha and the other crew are saying to me, these clients are difficult. Did I get my point across?"

And Sandy's words worked like a charm. Later that day, Aesha even admitted how shocked she was by how polite the group had become.

"All of a sudden, the guests seem to have this base level of decency," the Chief Stew recounted in a confessional. "Maybe they reflected and realized how horrible they were and this is their way of saying their sorry."

And when the charter was over, Mahisha gave the crew a glowing evaluation.

"Thank you guys so much, this was amazing," she said as her party disembarked. "I don't think we had any issues, did we?"

Aesha's reaction? "Were we on the same charter?!" she hilariously remarked in a confessional. "I mean, I'll take it for sure, but this is so confusing."

Keep reading to look back at some more of the wildest guests in Below Deck history. Below Deck Mediterranean airs Mondays at 9 p.m. on Bravo.

The Bravo franchise has had plenty of dramatic and crazy moments thanks to some unruly and demanding guests, including Georgia, who was a little too flirty with no-nonsense leader Captain Lee Rosbach.

Sometimes, you just want a foam party—at least, that's what this demanding guest asked for. Was it eyebrow-raising to see him drunkenly partying in what ended up being about four inches of foam? Yes. Was it still epic because of how excited he was? Also yes.

Where do we start with Delores? The season eight Below Deck charter guest made a splash, literally and figuratively, after she drunkenly jumped into the ocean late at night. To make matters worse, this swimming session was in direct defiance to Captain Lee's order to stay on the boat. In a first for his career, Captain Lee ended Delores' charter early and sent her packing.

However, while being escorted away on the tender, Delores jumped into the ocean. Bold move, lady.

Barrie boarded the Parsifal III with his blended family, including his current fiancé and his ex-husband, in season two of Below Deck Sailing Yacht. With such a large guest list, the crew was certainly put to work, especially chef Natasha. Not only did Barrie have no problem sending his breakfast back, but he also refused to have his family served buffet-style.

The first charter of Below Deck season eight was certainly a memorable one. We're, of course, talking about when the charter guests found themselves bickering over deckhand James Hough. Specifically, charter guest Shay called dibs on the British yachtie. However, her boatmance hopes were derailed when pal Lexi flirtatiously rode a jet ski with James. Thus, a fight broke out over dinner, which shocked the Below Deck crew.

It was ladies night on the high seas in this episode of Below Deck Mediterranean, but as the drinks flowed, some of the women started to get a little handsy with deckhand Jack Stirrup. Thankfully, Captain Sandy swooped in to save the day.

The crew aboard this ship got a show they didn't ask for when two of the guests hooked up in the crow's nest, a part of the ship that everyone could see on camera.

In the same episode that the crew witnessed the on-deck hookup of two of their guests, they also discovered that their passengers also had never heard of cleaning up after themselves when they stumbled upon a used condom on the nightstand.

For the most part, the charter guest is always right. However, in season two of Below Deck Sailing Yacht, charter guest Erica requested that Captain Glenn Shephard do something to make the ship stop rocking. Unfortunately for Erica, they were in the middle of a thunderstorm and Captain Glenn didn't have the power to control the weather.

Other highlights from this charter group include a woman with hours worth of stories, bullying accusations among the ladies and so much more.

While many guests on Below Deck have been demanding, this may be the most ridiculous request because of how random it was. On one of the episodes, guests demanded gumballs, but not just any gumballs. They had to be colored gumballs and they even threatened to require they be delivered by helicopter if there were none on board.

Not every guest has found their trip to be a five-star experience, but usually they stick around to give feedback as to why. On this episode of Below Deck, we learn that a few of the guests straight-up ghosted upon arrival and fled the ship before even saying goodbye to the crew.
