Nuts seem to be the worst, followed by shellfish. I have a buddy that has fits with fruit, only soft fruit, He says its a texture thing. If he eats a Kiwi it's barf o rama. Thats where I get the mind thing from. One of the coolest customers that I had, She had business cards printed with what she was allergic to. She would have the waiter bring it back to the kitchen and I would put it on the line for my cooks to see. I thought that was a cool idea. That way we wouldn't have to remember all the things that would make her do the " Tuna ".
