Yeah, I can't stand that. There are subtle techniques waitstaff use to be vindictive. Disappearing because you weren't ready to order when it was convenient for them is one. Happens a lot, in my experience. Ignoring you when they forgot to fill your water or bring more bread etc, etc. Funny thing is, most think they can fake it by looking busy. I know when you are ignoring me. Apparently the size of your tip is irrelevant to you. Sometimes I purposely forget to ask for a condiment or such, and make them come back four times when one trip would do. Another thing they do that is annoying is they come over exactly when you placed a forkful of food in your mouth and ask "how is everything?" It's like your dentist asking you questions while his hands are in your mouth. They don't really want a response. . . And I never use Yelp to select restaurants. Judging food and the experience is very subjective, for one. And it's already known that the reviews are manipulated and many are created by owners.
