I'm usually the DD, a position I volunteered for, but I will have a shot or two early on. One club we play monthly knows we like Patron and provides a couple of rounds. The manager is a big time partier who loves to party with the band. He's closed his establishment on occasion to see us in other venues. He buys us rounds then as well. But I digress. I don't care either way as long as everybody holds their own. The singer does tend to get a decent buzz on and it does help him perform better. He's great with the crowd so it's not a problem. There were two back to back incidents where he went too far and that caused a a little band drama. But two out of 100+ isn't bad and it hasn't happened since.
