I get the feeling that it's also easier for the cashier to put it into the point of sale / ordering system. There are buttons for specific menu items, and then buttons to remove things from them, but no buttons to build a burger from scratch.
I remember working at the drive thru for Wendy’s. I learned all about some clever orders that saved you $0.50-2.00 by ordering things a certain way. I can’t remember anything specific, but I remember one time asking, “so you want an X?” And they came back with “no, put it in exactly how I told you.”
