I like booze. I REALLY like free booze. There are so many kind people in the audience that buy the band a round of drinks. To this day, I am flattered that they would be so generous.
But when some sends up a round of shots, things get dicey. I am not gonna drink a shot of Captain Morgan. How do you acknowledge the generosity, but avoid drinking something you hate? Just look at any plants near the stage. They are soaked with booze. :)
