At 03:30 AM the diner menu was still on display. When I attempted to place my order, an original chicken sandwich with onion ring, I was told in a rude tone that it was only breakfast being served. I then said, I said I do not know what is on the breakfast menu I received no response. I waited a moment then backed out the drive thru and was not able to place an order. It seemed the employees had no desire to served customers at this time.
