I need a sense check. I was eating a biscuit on a national rail train yesterday. It had a peanut butter filling.
I was standing in the gangway as the train had almost no seats.
At one stop, a woman and 2 young children were getting off. As they were waiting for the train to stop the woman said to me you can't eat peanuts on the train as it's a confined space. I didn't immediately understand and didn't really respond properly. She then got off.
I feel humiliated and stupid. I knew sometimes on planes this wasn't allowed if someone was allergic but didn't know this was the case on trains.
AIBU for not understanding?
