Manager not adhering to Covid19 regulations

I was at OB britsmall while waiting for my order i noticed the person handling my order talking over my food while not wearing a Mask, when i asked why he is not wearing his mask, yells at me saying i shouldn't disrespect him in his restaurant by talking nonsense then he took the back the food, we were standing outside because its was takeaway .So we waiting think that he will place another order, a few minutes later i go inside to ask i and he tells me that i should leave because clearly i don't want food. I ask why is he acting up and giving me attitude, "you the one with an attitude to come in my restaurant and disrespect me,we test everyday and sanitize. You have no right to come here and tell me to put on a mask. Don't come here with your nonsense "he said Everyone else in the restaurant was wearing a mask except him because he is "the boss" i guess and taking temperature every now and then doesn't mean don't have covid 19 he didn't even want to tell me his name beautifulhe knew his wrong . This reckless behavior needs to be addressed.
