AITA? i feel bad

so i work in a cafe where there are constantly some events going on, today we had a conference (150 people attended) line was long. some other people came in and were like “can you ask what kind of nuts does this pastry include, im allergic to peanuts” the line was like 10 meters long and i was panicking and everyone else was doing something so i said sorry i really dont have time for this and if youre allergic to nuts i wouldn’t recommend anything really??? and then they rudely said okay fine well find some other place to eat. i feel supersupersuper bad but also fuck you for asking that kind of a question during a rush. im also dealing with social anxiety and theres a chef im reallllyyy not fond of (no one is) and whenever i ask questions she crashes out.
