It was a late night shop, 29 minutes before closing. There is another location less than a mile away but they probably encountered the problem late enough that they thought they would just deal with it the next day. I did not ask the reason but I did ask if they were any other options. The guy offered me a grilled cheese as a side. Then he asked if I wanted fries or a drink.
They were not going to open the fry station before they closed because the manager was cleaning it. As for the milkshakes, total mystery there. So far I’m still waiting for a reply from help desk, and for my shop to appear in the Assignment Status list.
