must also regulate fluid intake so as not to have to go to the bathroom before the last encore. this means little beer.
once upon a time when I was young I would go and drink all the beer I wanted. if that entailed leaving my place at the front I would go get the beer and work my way back up front without much problem. ditto if I had to go to the bathroom. for some reason I no longer find it easy to regain my place and I don't know if this is because the crowds are bigger or if I'm more polite than I used to be.
