This morning I was rudely awakened about 4.30a.m.(I think) by a naked man, standing at the end of my bunk and relieving himself on the dormitory carpet! (Keswick YHA) :w00t:

My response wasn't the best. My immediate thought was to shout something along the lines of "oi..what the hell are you doing!?" or words to similar effect.
But then I thought...he's either:
Totally trolleyed or asleep,
and considering his trajectory was in very close proximity to the bottom bunk just across from me, I realised that I may not be thanked for startling him!
There were no suitable containers to hand and by the time I'd thought about it some more, he'd crawled back into bed and was snoring his head off.

I was wondering how forumites would deal with such an incident, what would be considered as best practice?
