Well at the risk of being called one of these culprits, I put my hands up to having a couple of drinks at the airport bar (no more than 2), needing to use the loo a couple of times during the flight and also going for a little walk. I don't stand bent over with my backside in anybody's face, don't chat on top of my voice and didn't think I annoyed anybody. It seems I've been wrong all these years Didn't realise people were counting how many times I got out of my seat and cursing under their breaths. It adds another dimension to people watching.
