As I myself have worked in fast food for two and half years at one point in my life, I hear ya. Some people just cant comprehend some of the concepts a fast food restaurant has.
One night I was closing at the food place I was working at(Taco Time) and we had a special that night for two bean burritos. This one guy in a Mercedes pulls up to the drive-through and wanted to get only one of the burritos and expected it to be the special price cut in half. Which I sorta understand the guys point of view but I couldn't just manually put that into the cash register. Either way thats not what the special was intended for and the guy threw a fit. The only thing I could do was recommend for him to go file a complaint at the main office :/
