I went to Warsaw on my stag do with 7 close friends in March (on BA naturally).
The flight over at 12pm ish was quite busy and we had already had a few shandys at the airport, we asked for vodka (to get into the polish spirit as it were), beers and wines. The crew realised we were on a stag do and catered for us accordingly.
We were all very polite and not perticularly rowdy so were given 'special' treatment and given plenty of alcohol. we were pressing the button quite a few times but the crew were always nice.
Quite amazing how much you can get through in a 2hour flight!
