The drive thru workers here is either dumb or incompetent or both. He didn't know that you can add an extra patty to a cheeseburger happy meal. He consulted with another worker and add it as an extra sausage to charge me more. Never had this issue with any other McDonald's drive thru or the self serve kiosks. Instead of simply adding an extra patty he added an additional sausage for $3.09
