It was planned, but I covered my ass last night for the most part.

Used the concert venues owners kids has helpers, paid them more than dad but inline with the national average and within my state guidelines. Sold about 5,000 cans of beer before I was supposed to start selling them.. I don't really see Budweiser getting very upset about it though.
Both bands heavily promoted us. $4.00 beer at concerts don't happen all the time.
