I do recall a party held by a a previous employer at a top class London hotel where they were only serving wine & beer, neither of which I drink.  So I popped out to the local "offie" and bought myself a bottle of gin which I put in my room.  During the night I made numerous trips up in the lift to refill my glass, each time taking longer & longer!
By the end of the night my husband was holding me up on the dancefloor and I passed out later on in our room.  Trying to be cool and sophisticated at breakfast the next morning was quite an effort!
