I know that it's ridiculous to think that peanuts shouldn't be in restaurant food items, but it's kind of ridiculous how unprepared/unconcerned some restaurants seem to be about it.
I'd be curious to get Kwik's take on this. I saw a friend last year go into anaphalytic shock when she ate some fajitas at a Mexican joint. She specifically informed the waiter that she was allergic to avocados, then told him that even if the knife had previously touched an avocado it was no good, and still damn near died.
