Went to a restaurant, stated a dairy allergy as I EBF and DC has CMPA but did explain the situation that the allergy wasn't directly mine. I ordered a sandwich that on the menu came with cheese, but as such was not listed as "dairy free" on their app. I requested no cheese, again explaining the allergy situation.
The sandwich (grilled chicken) arrived and as I was eating it I noticed there were small bits of melted cheese on the edges - it was clear the cheese had just been peeled off rather than a piece of chicken cooked without adding cheese.
I know the dish wasn't listed as dairy free, but given the only dairy ingredient was the cheese, AIBU to say something (not asking for a refund, just making a point)?
