The entertainment was good. Joe Duece should have been the main comic. He was hilarious. Only reason for only 3stars is I had one drink for me, one for my wife. Near the end of the show my bill is brought out which is $23. I put down $30 and never see my waitress again. Pretty sure there is an 18 % gratuity added to the bill, so if i want to add to that i think that should be my option not her assuming the change is hers. A$7.00 tip on top of 18% is pretty nice. I may have to quit my job and waitress at comedy caravan if that is acceptable practice.
