I don't drink alcohol. It's true, I do not drink ever, and certainly not at a show. So what do I tip then if the band gets free drinks? Do I really give them a dollar for a 2 dollar drink? I can't tip the price of the drink, that would be even more odd. And then to take it to the extreme, my girlfriend will almost certainly have only water. I may go that route on some shows, too, to preserve the voice and because I don't HAVE to have pop. So then what do you do?
