I think over the last few years cabin crew have got stricter especially with groups of young people and the tolerance for people being drunk is getting lower, every few months its reported about drunk passengers getting thrown of planes. I was sat at Dalaman waiting for a 22;40 Easy jet plane and it had been delayed by over an hour I could actually see the plane parked at the other end of the runway when we eventually got on the plane I asked about the delay and was told that they had a very drunk women on and had her taken of the plane when they landed the delay was waiting for the police to turn up. The stewardess said that women would be taken to cells then when she had sobered up she would be put on the next available flight back to the UK at her cost she also said why should she have to put up with that type of behavior while at work. I worked as a night club doorman for over 15 years and we never put up with that type of behavior so why should she I know its only a slogan on a T shirt but the cabin crew have to take everything in to consideration for all we know they might have been a little on the drunk side and didn't want it to escalate but I wasn't there so don't know
