Wow-I just saw a preview for the next show, Wednesday I think. They want the cake decorater to decorate the cake as a form of entertainment during the reception! He has two hours to get it done.
I don't even know how a person would begin to price that cake, but I think starting at base rate*10 might be fitting .
