Flight attendants sometimes witness appalling behaviour from passengers, but they're not going to take it lying down any more (unlike some of the travellers). Former flight attendant Shawn Kathleen has set up Passenger Shaming, full of photos of airline passengers engaged in inappropriate behaviour.
The photos on the site were taken by other flight attendants or submitted by outraged passengers. They include shirtless men, women giving themselves pedicures, a man watching porn and a lot of bare feet. IBTimesUK presents some of the best (or worst) examples.
