Yeah today at work serving some kids and they said "so what ese are you, Chinese, Japanese, tawaniese" they all started laughing until I told all counter staff not serve them and I'm getting sercurity.
Takes a certain type to go out of their way to be purposely offensive to someone they don't even know. Says much about them. It was racially charged and totally unnecessary.
You can refuse service to anyone for any or no reason. Obviously you know that. I'm just saying.
