Burger King review: Asked for a tip; cheated a whopper sandwich

At the end of March last year a new employee told me because of the covid shut in, he wasnt making much money and begged for a tip. Burger King needs to keep an eye on the employees in this location which is at University and power in Mesa, Az. Today I ordered 2 whoppers and 1 double whopper. It showed on the drive through screen and said 12.01 price. When I got to the window a girl there looked confused. Then somehow she realized she messed up and walked away from the register. Another girl took over her place, still charged me 12.01. The very guy who had asked for a tip before was standing there laughing and looking sneaky. The girl who rang me up had a look like she knew they were doing something wrong. I got home and just had 2 whopper sandwiches
