I use to work in a Grocery Store; I tried to do my best.  There were certain customers who came in, to put you to the test.
While ringing up their groceries, I politely shared my smile.  I stool behind the counter, watching a woman screaming out at her child.
Some customers fill their baskets, to the very top.  Only to find just a little money, and that they forgot how to shop.
Some customers walk around, taking their own dear time.  Then, when you wait on them, they expect you, to quickly get them out of line.
Some customers seek attention, especially, in a crowd.  They carry on a conversation, not softly, but they speak out very loud.
I recall one of my customers; who fail to show respect.  He flaunts around in a long white robe, rubber boots and a big cowboy hat.
