Burger King review: Drive thru cashier

I have a 30 minute lunch so I placed and online order to pickup. I got there and the drive thru was 8 cars deep so I waited for 5 minutes and it never moved so I decided to go in hoping it would be quicker. I get in and there are 2 people in line and realize they are VERY short handed. An older lady was in front of me turns around and starts talking about how it was a mistake for her to stop there. She ordered and paid and was waiting on her receipt and cup because they cashier walked away, and she said it would be nice to get my receipt and cup so I can fix my drink. The girl in the drive thru came over I told her I placed my order online and she started running her mouth about being shorthanded. I told her I didn't say anything she then pulled my order still running her mouth and handed me the receipt I reached up and got it out of her hand she claims I snatched if, with the way she was acting I hope I did really snatch it. She gets even louder saying some words she should not have been saying in front of the customers especially the lady with kids at a table. She got mad and told them not to give me my food and I said that's fine give me my money back she said you ordered it online you get your money back online I said show me how she said that's your problem you figure it out. I asked for the manager and what a surprise she was the one standing right there and never said a word. I told her to either show me how to do a refund or give me my food. she got my order ready the other girl still running her loudmouth starts hollering as I'm leaving and I am hollering back. The cashier and the Manager are pathetic neither one needs a job there, they are making your company look very bad. I don't work far from that restaurant and our whole business refuses to go there because of the employees and how long it takes to get your order. You need a real Manager that can control their employees.
