I’m not sure that complain is the right word. I don’t like people that complain. There’s not much that could happen to me in a restaurant that would even get me to make a comment or a suggestion.
If I don’t like the food, that probably has to do more with my actual taste preferences than anything else. If the food was cold or burned or the wrong item or there was a bug or a hair in it, I would just politely ask the server if they could fix that situation.
I’m always mortified to be with any person who sends back their steak or that kind of thing. One man’s medium well, is another man’s medium and another man’s well done. I think it’s ludicrous that people think there is an actual true meaning to those types of words. It’s true that there are internal temperature settings that chefs use, but most people doing the actual eating have an idea in their mind about how done their meat should be, but it’s completely subjective. I kind of feel the same way about the cork sniffers. I just want to crawl in a hole and die when that happens. I have an aunt who routinely complains about the wine and then sends it back. It’s very embarrassing.
I also don’t like people that complain that they don’t like the taste of something. My best friend’s boyfriend does that all the time. Problem is, I usually love almost everything that I’ve ever tasted in any restaurant that I’ve ever been to and he’s hated almost everything he’s ever ordered in the exact same restaurants. I love food. He’s super picky. That is not the restaurant’s fault. Also this dude has certain ideas about what certain dishes should taste like and if they deviate from his idea, then he gets all irate. I, on the other hand welcome nifty variations on dishes that I’ve grown to love. Take macaroni and cheese for example. I’ve eaten mac and cheese in umpteen restaurants over the years. Some was great some was so so. But that is because of my own taste preferences not some fault of the restaurant.
I would very politely and discreetly ask the server to take back an item that turned out to have meat on it, when it was listed as being a vegetarian item. It happens, but it’s not worth making a big stink about. Actually the other day my folks and I were out to lunch with some relatives. I ordered a Portobello burger, which I oft have, because it is sometimes the only vegetarian item on the menu. Unfortunately for me, this was a real hamburger with a Portobello mushroom on top of it. My mom, who actually does eat meat ordered the same thing. She took one bite and then pinched me on the leg and whispered discreetly into my ear that it had meat on it. So we just grabbed the burger patty out of the bun and flipped it onto her plate. My relatives just kept on chatting and nobody even knew. I think if it had just been me and my mom, I probably would have asked for something else, but I really didn’t want to cause a scene. Note to any potential restaurateurs, please be very specific about ingredients on your menus!
The only thing that is likely to get me to complain or voice concern, is when the wait staff or host or server is rude. And in that case, I would likely write or phone the manager of the restaurant and let them know exactly what happened and who the culprit was (I would get the name of the rude person before I left the restaurant).
If a restaurant is too loud because of the physical acoustics of the place, I might talk to the manager and suggest that they put up some sound baffling equipment, or maybe consider turning the music down just a tad (not a complaint, but a suggestion). It it’s just too unpleasant for my ears, I just might not go back again. Some people love that kind of raucous environment, so again, it’s my own preference, not some horrible thing done by the restaurant to offend me. If I’m seated directly under the air conditioning, I’ll just ask if I can be switched to another table. No complaint, just a request.
Most stuff that goes wrong in a restaurant is not something that happened on purpose. If a restaurant is super busy and understaffed, you might get your food a little bit late, or not get all of your items in the order that you wanted them, or something might get forgotten. Sometimes the wait person is new and might get the orders a little mixed up. That is absolutely nothing to scream at her for, or to publicly humiliate her, it happens. A few polite reminders and a nice smile are better ways to get what you want than becoming the restaurant equivalent of the Ugly American. I also send notes to the managment when I get great service, and I name names.
