One of the small time weekend warrior cover bands I play in was playing a place we had not played before. Against my better judgement we agreed to 'you need to bring 25 people or we are not paying you the full amount for the gig'. I had never played a gig like that before but the drummer wanted to play there because it is close to his house. I agreed to it. One, 98 percent of the time we have more than that there at least part of the night. Two, money is definitely a secondary reason I do this so I think - so what. Well anyway 2 minutes after we get there and start unloading the owner starts asking if we are bringing out a crowd. We say yes, we don't know how many but we expect quite a few. He's completely drunk, the place is a bit shady and I'm not feeling too good about this. After first set (we played pretty good) the guy starts telling the drummer who booked the gig where's your crowd blah, blah and says he's cutting the gig pay. We have about 20-30 there and it is at least 1/3 of the people in the bar. We say may be second set we are going to have some more. Well eventually a few more come out. We didn't have a stellar crowd but at very minimum it is like 30-35 and a decent percentage of the people in the bar. In the end the guy wouldn't pay the whole amount. Any way rough night. Crazy thing was that a few of our regulars caught wind of the situation and pooled some cash for us and tipped us. We actually end up making more than we usually do although I feel bad about that. We don't run a tip jar so typically tips are from strangers for requests and are small. Nightmare situation and I will definitely never do that again. I think the owner was just looking for any reason to stiff us. Any way it was my fault for doing the gig. Lesson learned.
