Yeah, my wife knew a woman who died from a strawberry blizzard at DQ. The machinery had been in contact with peanuts.
My gosh....if you have an allergy like that, you probably should never eat out. You never know, right? I guess the school's that ban the peanuts do have the moral obligation to do it. If you know for sure there is a student in the school who has this horrible allergy, then I understand banning peanuts from the school. Wow...you learn something new everyday.
