I run a fair show for everyone. Some of my singers are shall we say, less than average and I have to say that while they are singing, I am mentally banging my head against the wall, but as has been pointed out, they spend money over the bar like everyone else and as sad as it may sound, karaoke might the only "life" they have. Karaoke is all about having the guts to get up in front of a crowd and being a "star" for 3 and a half minutes (unless it's a Meatloaf song) and having a ball in the process. I get paid to make everyone happy.
If you're too drunk though, sorry pal, may be next week
