Do use, or hear that much? In our household we must hear, or say it 25, to 50 times a day.
I say it more than many. But, less than I should. I especially try to say it to people with "Shiny Zero" jobs. Jobs where no one notices anything they do until they mess up. eg; Church secretary /clerk, custodian, piano player, treasurer... At the grocery store, the young woman who bags my groceries AND puts them in the cart while I am paying the tab... Etc...
