Will they empty the fridge for you if you asked? I always bring drink on board, then play the in out game with the fridge. I have in the past just stored the original contents in a box and placed it all back before leaving. No idea why i've never just asked them to take it away.
To add to others no limit chat, I have a little pull along case just for this. If you opened it for a week there is normally 2 bottles of fizz, I bottle gin various tonic, a small bottle of baileys and a couple of bottles of water and a OJ. Feel free to knock the door if you want a night cap! We don't drink "that" much there are three of us in our cabin.
