>certain the stores and even individual employees are rated on how fast they get the orders done

They weren't fifteen years ago. The only speed incentive was not pissing off the customer. That may have changed, I can't say.

One thing I didn't consider earlier, if the store is busy enough the oven might be full and the cook hits the button to clear the entry they're done with so they aren't confused.
