Got a cheese danish thrown at me

Currently in the bathroom typing this but a customer got upset because he was waiting for his food (we were down a partner and Fridays are hella busy) and he started swearing at one of my partners who has a mental disability. I kindly told him if he was going to swear I will gladly refund him. He then threw his danish he was holding and said forget the other sandwich. Now I’m contemplating on leaving. How’s your day going?
