Oh, and you'll laugh at this one.
My buddy was the first person to ever ask for a locals discount at that window. They hemmed and hawed about it, saying that it wasn't available, but finally the manager on duty authorized it, partially because my buddy is a Seven Stars.
Anyway, someone from upper management audited their sales for the day, and found that he was given this locals discount.
Upper management hauled all of the shift managers and assistant managers into a meeting, and yelled at them for allowing this to happen. They were told in no uncertain terms that they were never to offer a locals discount again at the window (though it IS allowed in the restaurant!)
The reason they were given? "Because the window is already so discounted."
Yet it's not actually discounted. They just give you far less food.
