You work in the fast-food industry.... you don't need to be a rocket scientist

This is true, but when it's never been an issue in year before..such thought process isn't deemed as needed and thus a routeine develops.

Granted, but she might have been new. You never know.

Reminds me of the customers at QT when we had the "4x Pepsi 12-Packs for $10" and "4x Coke 12-Packs for $10" deals going at the same time. Customers always wanted to mix-and-match.

Cust: "Well can I get two Mountain Dews, a Pepsi, and a Diet Coke?"
Ran: "No, because Diet Coke is a Coke product. It has to be four Pepsi OR four Coke products."
Cust: "Well, what about two Mountain Dews, a Coke, and a Diet Coke?"
Ran: "Again, no because you can't mix and match."
Cust: "Why not?"
Ran: "Because that's not the f*cking deal you degenerate @sshat!"

Okay, so maybe I didn't say exactly those words but you get the picture.
