I was sitting at the fast food table, a lady came up to me and asked me if she could sit at the same table as me and I said yes, the lady sat at the table and a few seconds later a boy came to take our orders, the lady said she wanted a snack with mayonnaise and the boy said mockingly: "you got fucked because there's only ketchup here." The boy was so direct and rude to the lady that it left me and the lady surprised. The lady started to offend the boy and apparently the boy didn't like it...
