Temporary Tourettes
After working BOH a number of years, I spent a few waiting tables (fine to diner, in that order).
Regardless of which side of the house you work, it's possible to make the night miserable for the other. Example, a waiter can send in four tables at once, and spend all night suggesting only sautee items. "Got enough pans, buddy?"
On the other end, the kitchen can toss a plate under the salamander for a bit, or just fire one persons tables all at once.
Either way, the whole place suffers. Working as a chef, I always keep it in my mind that the kitchen's job is to help the waitstaff get the best tip possible on every table. I am the only chef that I know of that takes this approach, but I will tell you that it works like mad. It can make life in the kitchen a little harder from time to time, but if the FOH knows what the limits are, they can make the guests feel welcome and everybody wins.
I can think of a couple of restauraunts that my wife and I have been going to for years because the food is good, but more importantly we have a specific waiter that really knows how to treat us. Don't think so much of yourself in the kitchen, food is only half of why the guests come in. Food is an entertainment expense for the guests.
Granted, there are restaurants that ARE just about the food, in my experience they are holes in the wall with shabby decor and cheap meals that would blow your socks off.
As for swearing, you'd think that I had Tourettes if you ever saw me talking to my work table. Most kitchen have foul language, tasteless humor, and goings on that would constitute serious sexual harrassment lawsuits in any other industry. Imagine calling somebody the, "Typing B***H," at an office, or the "Cash B***H" at a grocery store. "Grill B***H," no problem.
My first day on the job at the first hotel I ever worked in, I had been told that the chef's nephew was a real pr**k. Apparently he'd be getting in my face and giving me a really hard time for the first six months or so. About an hour into the shift he gets real close and starts in on me for nothing in particular. When he was done, I calmly said, "Hey Rick, ever had to pick up your teeth with broken fingers?" He was quiet for a few seconds and then laughed and said, "I Liiiiike youuuu." Then we were good. Not swearing, but words I could never use at a bank.
So, IMO, Tourettes is a part of most kitchens... No big deal.
FOH people are as important as BOH, almost always. Treat them well, and let THEM buy the drinks after the shift.
