I assume every order from a fast food outlet has something wrong. It is the nature of the beast. So I don’t get upset about it. The best thing you can do is check the order before you leave the drive up window. If you want to escalate it, return, walk in and explain the problem. They will fix it. You don’t have to yell at the workers.
Excellent attitude but had me musing. All these wrong orders. But are they ever in our favor? Do they give us a large shake instead of a small? Two burgers instead of one? Unpaid for fries? Or is it always less?
