Hmmmmmmm......not too sure about this
The problem with option A is well, you make no damn tips but then you are not running around like a chicken with your head cut off because you have tables all over the damn resturant.
The problem with option B is that you have tables all over the damn resturant.
If this were a small place and you didn't have to sing a damn birthday song every five minutes or have to try and round up birthday singers this would not be a problem.
But this place is huge, people are demanding, the ice cream melts instantly and rounding up birthday singers is a pain in the ass.
This is not going to go well, mark my words.
