A while back I remember reading an article in the New York Times regarding the word "NO!"
More specifically, a story about NYC chef's, notably David Chang and April Bloomfield, who are saying "NO" to customers!
It is not an ego issue; it is not a control issue (per se); it is not being obstinate.
It is simply that sometimes the customer is NOT right! Is it safe to come out yet? Well, let me explain...
Every cook and chef that works in a kitchen learns how to cook the food that is being served using what is essentially muscle memory. Preparing the same item the same way hundreds, if not thousands, of times is what enables us to prepare somewhat complicated dishes within an acceptable time frame. The last thing I want a cook to do is have to think about what he/she is doing.
We don't like your order hanging around the kitchen any more than you do...
Now, you throw a special request in the works:
"Can I have the sauce without mushrooms? Can I get the lamb without the cumin rub? Can I..?"
While I want you to have the most spectacular time whenever you come into the restaurant, I REALLY do...and I REALLY want to try and accommodate your request...these requests can derail E-V-E-R-Y-T-H-I-N-G!!!
Creatures of habit, rewriting the menu on the fly for everyone who walks through the door with a special request, cooks do not deal well with these monkey wrenches; they could indeed lead to your meal not being what you expected...and could absolutely ruin Table 22's night as well. Yeah, the really nervous guy behind you that was going to propose tonight...
If you have a food allergy, we will accommodate you gladly, but please tell your server...NO, make a reservation ahead of time and let me know that you are coming. Forewarned is forearmed: you will have a spectacular experience, (again, the cook does not have to think to execute)!!!
I truly believe that when you come in to my house, I will treat you like a guest; please respect the house rules...or at least give my menu a try before you rewrite it.
