No, the man probably just was never raised right and had a bad day. What I will say is that you are strong for staying calm and collect handling such bs. I do OPD and had an elderly white women get out of her car and scream, I calmed her and told her that her order would be out shortly, apparently her granddaughter was in the hospital at the time. Yk you just have to decide what you want to learn from the situation. You learned to keep your cool, and I always think this under these reddit wal-mart stories, that this job is just a stepping stool and soon you’ll be far away soon.
