I, too, read the book and wasn't too alarmed--but then again, I'm not a rude diner. I rarely send something back--instead, I go to dine.com or restaurantpoll.com and document my opinions on those sites. On the rare occasions when I send something back, I do apologize--and don't send something back in a nasty manner. I'm not apologizing for the nasty people in the kitchen who sabotage food--I think that's awful, but in college, I did a stint in a kitchen and rudeness is sometimes met with rudeness. For instance, I remember this one gentleman, he said, "And step on it." And, lo and behold, the cook stepped on it and put it in the "to go box." So--I do believe you have to be a bit wary. However, Bourdain's book didn't document constant nastiness like this. Basically, he gave the diner insights on what restarateurs do as a general practice. Case in point--most chefs feel as if those who order well-done steaks don't deserve the prime steaks because they can't tell the difference. Therefore, the cooks call these "reach-ins." They reach into the back of the freezer for the non-prime steaks and throw them on the grill to cook them into shoe leather. Another insight that Bourdain imparts upon the reader is that brunches are, for the most part, items that didn't sell during the week. I didn't finish this book and fear going out to eat again. It's fun reading and I recommend it for any foodies out there.
