Baggers, I couldn't give a toss how much you paid for your seat but when this Tesco class pedestrian needs to go he needs to go. I'll find the closest toilet and sequester myself in it for as long as I like.
Maybe it's time that airlines started to give 'penalty fares' to posters like the above, for using accomodation they have not paid for?
That aggressive type of posture is really not on.
