He kept his head down, taking orders as quickly as he could, not wanting to look up because he knew. He Knew that the line was out the door that he was taking too long. But there was only so much he could do when he was expected to be three people at once. 
Taking orders was easy.
Setting the food on the tray easy.
But trying to do that and half a dozen other tasks as customers kept coming up with more needs and requirements of him...made it difficult.
He silently flinches as yet another person leaves the line, headed to find food elsewhere.
If only...if only he had backup.

No one could help him.
No one could come get a second register open.
He exhales, turning to the next customer, hoping yet not believing that this would mean the end of the rush hour line.
