Grapefruit, I'm fine with it... although when I expect to taste cantelope and get grapefruit taste instead, it is weird.
My thing is peppers. Capsicums. Green peppers, red peppers, yellow peppers... I'm allergic, and they put them on and in *everything.* Ugh!!! Even the smell makes me gag. On SQ, you can order a special meal made without them, but not on UA.
