bad night is when i only have 4 people singing., and none of them is buying drinks..drunks, i just had one incident, this guy just got out of prison one day before my gig ,and everybody knows it and he wanted to sing "please release me" by E. Humperdinck and i told him he has to wait for his turn.but he just wont listen, make long story short he ended going back to prison for parole violation..the owner called the cops on him..
