I sure have. But you can add another category: sex. A few too many times when I travel and go out to dinner alone, the maitre d seats me far back at a table by the kitchen. Why? Because a single woman dining alone does not look good to a few restaurants; I've been told that blatantly. Whenever this happens, I request to be reseated at another table of the same size in a better location. Then I never return to that restaurant. It's 2004----what is up with these restaurant managers?
