Burger King review: a guy that work there

I came in today the 21 of sept i place an order. I have a coupon for a free wropper, i didnt know u have to order a side ordet witb it. But i order a chicken fries and a large fries he didnt put in the free whopper instead he charge for it. I told him i dont want the whopper no more. He said he cannot remove it, then he got mad nd piss off at me so he took out whopper he charge me and i paid for the other order he give back the throw the change at me. I told him you r so rude and disrespect to me. I told him I'm gonna report him look like he doesn't care. Really bad service i got for today. I hope you guys take this seriously or else he will do to other customers. Very very sad and unhappy customer.
I was there around 5:10pm Saturday the 21st of sept. Ty for your time
