A woman who worked as a crew member on a luxury superyacht has told how her millionaire boss ordered her to fill her bathtub with bottles of Evian mineral water.

Spanish beauty Giselle Azueta revealed the bizarre request in a video about her life serving the rich and famous at sea.

One unnamed passenger, she said, insisted on bathing only in still Evian mineral water and ordered Giselle to fill up the tub with it.

She revealed the bizarre quirk in a social media video which has clocked up more than 11 million views on one platform alone since 24th October.

Giselle said: “I mean, imagine filling a bathtub with only bottled water because the woman would only bathe with bottled water.

“It’s not a joke, we would order, I think, around 400 bottles of water a day, because, well, we could only get the 500-millilitre ones.”

Each bath, it emerged, would cost more than GBP 200 just for the water even at supermarket prices.

Giselle added: “It was crazy. I mean, I’m baffled when I say it, like, you guys, I don’t know, I don’t know what, I don’t know, would you bathe with only bottled water to fill your bathtub?

“I don’t know, it’s so crazy, who spends their money on that? Do you agree?”

Social media users were astonished by the demand.

One, going by ‘Albert Lopz’, compared her with 16th-century alleged serial killer Countess Elizabeth Bathory who was said to have kept her youth by bathing in the blood of young virgins.

They laughed: “Elizabeth Bathory had a somewhat more eccentric taste.”

While ‘Jocelyn Diaz D’Luz’ added: “But at least she was more environmentally friendly… the container wasn’t plastic.”
