I hung out with a tour manager of a 'big name' band and a bunch of other folks in his hotel room after the show, ingesting various substances, and otherwise making a ruckus.
The only thing we didn't do was smash up the hotel room. I did open a little plastic cup.. does that count?
The bottles of poland spring water they leave in your hotel room for you, cost $4.95 if you open them!!! insane. I didn't bother to check for a mini bar.
