Well, not really the intolerances themselves, just people who BANG ON ABOUT THEM ALL THE TIME. A girl I work closely with has a number of intolerances - fine, nightmare, must be difficult, and I sympathise, but I truly don't need to hear about them every day. Nor a blow by blow list of what the canteen is serving and whether she can or can't have it. Or to cover for her when she's off sick having eaten a truck load of "bad things" the day before and made herself ill.
Please let me know - AIBU???!
