Burger King

That burger king has poor management. A couple of days ago I ordered a meal and they messed up my order, so I was talking to a staff member and she got all frustrated and left the counter, then another staff members comes in and she dismisses my problem and tried to say that there was no mistake made, when there WAS a mistake made and she didn't admit it. So then she apparently gives me a "refund" but idk if she did i'll have to check my card statement later. While giving my refund she is arguing with me and as i'm leaving she says "you better not come back" but she has no authority over that. I'm very upset at this behavior of burger king!
