Two cruise passengers were left stunned after getting a member of staff having sex in their cabin.
Bobby, 64, and Mary Jackson, 62, were traveling with Norwegian Cruise Line from Singapore to their dream cruise.
Just after boarding the ship, they were confronted with the sight of a naked male crew member having sex with a mystery woman on their bed, The Sun reported.
"I was horrified, what I witnessed was extremely unpleasant," Mrs Jackson said.
"There was a man and woman having sex on the bed in our designated room.
"I immediately closed the door again.
"Eugene, our cabin attendant, was present and he immediately went to inform his supervisor.
"We are not prudes but this is ridiculous."
The couple, from Northern Ireland, had paid about $ AU8600 for the week-long cruise – their first ever – on the 2376-passenger Norwegian Jewel ship in October
But the trip to the rest of the tour when they were left waiting on the quay side at Singapore's Marina Bay for about two and a half hours scorching heat before boarding.
"When we finally got the ship we first went to the bar for a drink because we were exhausted after all," Mr. Jackson said.
"We were then shown down to our state room accommodation, which was really looking forward to looking forward."
When they got to cabin 10039, the electronic key card did not work in the door at first.
But at the third attempt, the door finally opens – and that is when their jaws hit the deck.
"I could see the back of a man on the bed, who was directly facing us and it was obvious that he was in the middle of having a woman," Mrs Jackson said.
"I shut the door immediately and we went into the cabin next door where my sister was staying while the staff sorted this out.
"I was traumatized and I needed a glass of water."
The couple went to complain to the ship's guest relations manager but they did not find any room available.
"We went back to the cabin and tried to go back in there but though the woman was left," said Mr. Jackson.
"Two of the ship's crew in white uniforms eventually persuaded him to leave. He saw very hideish.
"I asked if the crew knew him and they told me he was a worker on the boat."
The couple said they were "insulted" when they were offered the equivalent of about $ 180 of credits to the ship.
Things got worse when Mrs. Jackson took ill with a stomach bug two days later and spent most of the rest of the trip confined to her cabin.
"I was very frightened because I was very sick and I was a long way from home," she said. "The ship's doctor put me on an IV drip, gave me antibiotics and I was told to stay out of the sun."
When the couple returned home they wrote the Florida-based operators Norwegian Crude Line to complain about their experience but were unhappy with an offer of $ 360 each in credits, with the next trip firm, if taken this year.
The cruise company Norwegian Cruise Line said a full investigation has taken place.
They said the Jacksons have been contacted.
