I get mayo on burgers on occasion. Not all the time. It's something that I picked up on only recently. Otherwise, my burgers have nothing but ketchup, lettuce, tomato, and cheese. I don't like any of the other crap on it. I live in Chicago and the only thing I'll put on a hot dog is ketchup and, sometimes, cheese. Chicago-style dogs are the nastiest thing I've ever seen. People in hot dog shops around town will refuse to sell you a dog if you order it with ketchup or cheese. They say it ruins the flavor of the dog. How the hell does ketchup, by itself, ruin the flavor of a dog, but putting hot peppers, cucumbers, pickles, relish, and mustard on it does not? How you can even taste the dog through all that crap is beyond me.
