That's a **** ton of beer! I'm impressed
Wow! I mean, my band drinks at rehearsal, but we usually have about 16 beers between 4 of us in over 3 hours (our drummer doesnt drink), so that's like 4 beers a guy...no biggie. We all have 9-5's and when we rehearse two nights out of the week, we like to definitely let loose. It's fun, and you're supposed to have fun at practice...
But...that...is a TON of beer!
And at an AUDITION of all things?
I guess consider yourself lucky. Things could only get worse from there, I suppose.
Definitely don't ask the band what kind of beer they like at practice (for the next potential audition). This will throw them off. And they'll expect you to show up with it, also might think you're a bigger drinker than them. IMO Stick to your criteria: No drinking. You'll find people to jam with - even if it's church people
