That must have been terrifying for her- had she never eaten mangoes before, or did she not realize that she had had an allergic reaction to them in the past? They way I've heard it explained, your first reaction to something doesn't usually cause anaphlactic shock, but your second or third or so can cause it.

Yeah, anyone with any kind of food allergy/sensitivy is a pain to shop with. I have a food sensitivity to some food preservatives.... technically it's not an allergy, although I have a couple of those too, and I usually explain it to people as an allergy- makes everyone's life easier. It's a massive annoyance- I have to read the labels of everything I buy, bring my own food on flights/to work/everywhere, bc I get very sick within 20 minutes of eating or drinking either sodium benzoate and potassium sorbate. My friends are really good about it, having seen me get sick a few times- they won't cook anything for me without carefully inspecting all the labels.

The upside of it is that I don't care how bad airplane food is, because I can't eat most of it anyway. If it's not fresh fruit or ice cream or in a package with all the ingredients on it, I'm not touching it.
