I have an aunt who is a very picky eater, but a restaurant meal is not complete without her letting everyone know very loudly about her dislikes. Even though she orders virtually the same bland things every time, she will grill the servers in great detail about the specials, making them describe each nuance of the dish at length, sometimes having to run into the kitchen and check on the answer. After she has run them ragged, she will then shriek, "Yuck! I hate that! That sounds disgusting!" so everyone within ten miles can hear, and go ahead and order some plain grilled salmon or steak. She is in her 70's now, but has been doing this forever.
