Flight attendants have revealed some of the worst pick-up lines they've heard while at work.
Being on a plane is an experience different from any other, with unusual levels of tension, people feeling uncomfortable, high air pressure and occasionally lots of alcohol flowing.
As a result, passenger can find themselves overstepping the bounds of social convention and trying on their luck with the flight attendants as they go about their job, The Express reported.
Rich and Andrew are two flight attendants who write about their time in the sky on blog twoguysonaplane.com, which also offers flight tips, deals, and insider travel hacks.
They’ve also witnessed all sorts of things on their shifts, from people being drunk and disorderly, to passengers attempting to join the Mile High Club.
When it comes to cringe-worthy chat-up lines and rude comments said flight attendants, they’ve listed the most egregious.
On one occasion when asked by a flight attendant what they would like to drink, a passenger boldly replied: "You, on ice."
The consumption base attempt at romance was continued by another hopeful customer who remarked "Well, would you look at that -a snack from a snack." when being handed a small packet of pretzels.
Another incident saw a passenger attempt to give a flight attendant their number by writing it on a piece of paper, which they pretended was a bit of rubbish they had found on the floor.
But none of these unsolicited advances are anything compared to the violent and rude behaviour Rich, Andrew and their fellow cabin crew members occasionally have to endure.
They recalled how on one occasion, on being refused a beer, one passenger told a member of the crew: "You’re an overpaid vending machine."
Another drunk passenger, who had been cut off, threw their popcorn all over the floor, while another tossed their bag at the flight attendant when there was not enough space in the overhead bin.
The most shocking incident the pair claim to have witnessed is a passenger pulling a flight attendant’s ponytail to get her attention so they could order more snacks.
While such bad behaviour is clearly unacceptable on a flight, it can be difficult to work out where the bounds of politeness lie in an environment that straddles an odd line between public and private.
For example, the sight of a pair of un-shoed, un-socked shoes on a commercial jet seems to inspire fury and revulsion in people more than almost anything else.
Pictures of people propping their bare feet up on the tables or sliding them onto the footrest above regularly evokes thousands of horrified comments when they're posted online.
As foot-phobic as the population may be, flight attendant Marika Mikusova insists that it can be absolutely no problem to take your shoes off on a flight, if you adhere to the unofficial code of conduct.
The Diary of a Flight Attendant author told the Mirror: "If you occasionally shop for nice but uncomfortable shoes like me, feel free to take them, off on board. Just watch out for the odour.
"Cheesy feet may be very annoying not only for your fellow-passengers but us – the potential life saviours of yours."
The Czech aviation worker also invited passengers to wander around the aircraft without their shoes on if they wanted, but urged them to be prepared for the consequences.
"If you want to move around the deck without shoes – first, thank you for mopping the floor in the lavatory, second, bring a spare pair of socks," she said.
"When you land, you'll probably want to throw the old ones away. At this point, your socks have already got their own ecosystem, and their residents may have already elected their mayor."
