This flight crew was obviously just coming off a flight or they wouldn't be there WAITING for their rooms
If their rooms weren't ready, should they wait until their rooms are ready, change then come back for a beer? By the time all that happens would they be to the point where they wouldn't be allowed to drink?
If their rooms weren't ready and the hotel messed up, what are the chances the manager put them in the lounge and allowed them to order pizza as they couldn't change and go get some food?
I mean if I had just finished my work day and got told no hotel room for you, I would be pretty upset, maybe they were making the best of it. I am sorry it ruined your drinks...
