One thing that I hate watching (while I’m waiting for my order) is when a chain has an insanely complicated menu, especially when they’ve combined chains like a Taco Bell / KFC, and the staff have to scramble to deal with all of these different items as one-offs in a tiny workspace, while continuing to priority-service the drive-thru.
I bet the staff turn-over is high.
Meh. Have a limited selection of signature items, make them good, make them fast, but what do I know?
