Agreed Marty. The connection between the kitchen and wait staff is very important and I was always very happy to hand over the 2.5% that I was meant to.

I would also buy rounds of drinks for the kitchen boys on a busy night where we were going crazy with turnover...the behind the scenes guys are half the reason if a diners experience is a good one or bad...the kitchen, hosts, etc. are all part of the "show" that gets the tips flowing.
