No no. Too short sighted. You do what you said, but at the end, ask for the manager, tell them that she treated you differently because of (skin color, male, female, had a trump hat on) etc and then tell the manager that she should not be allowed to wear such an offensive mask. And moreover, she should be paying for our meal because I'm not. Stick it to them hard. When these places feel the money pain, they'll get on board the Trump train or get run over.
