Once a week I like to go to sonic and get a burger i always get the same thing the total comes out to 8.06 and i always pay with a 20 and change. The last 4 weeks ive worked there ive been waited on by someone new and all four times shes tried to either not hand me the 10 or hand me the 1s and a single 5 dollar bill. I call her out everytime and she always says the same thing "sorry I'm new" which doesnt make sense because being new has nothing to do with basic math. I like to think this is a simple error but 4 times in a row every time i go seems intentional. Regardless of if shes doing it intentionally or if shes bad at math I feel like that many errors should get you fired. I'm considering calling in and telling her manager. The reason being ive seen other people complain on facebook about the same thing. Would i be in the wrong for doing this?
