This is very true. I was at my retail job and a customer walked up to me while I happened to be leaning on my workstation because my back hurt. The first thing he says to me is, “when I had a fast food job, if there was time to lean, there was time to clean!“ I looked at him, and then I turned around and walked away. He had this stunned look on his face. I walked into the back room To cool off a bit before I walked back onto the floor. It was probably five or eight minutes. When I walked back out, he was still standing there, at my workstation, waiting for me.
