let me also ask this specific question also...
Why do you think your good enough to perform in front of paying audiences?
DUHH, I guess if the audience pays and then doesn't boo you are good enough?
or in some cases Don throw beer bottles at you

then again depending on the venue.....people will come to eat not knowing who or if they have entertainment so once they sit and order they are stuck with whoever is on that stage ...the hope is they are as good as you

.....otherwise it's a dinner experience from hell ....
