SCM TIP

I was working as a greeter at my favorite box store when a woman came up to me as she was leaving. her hands were full with at least a dozen shopping bags and she made the comment: "what would we do with out automatic doors?" This always gets my goat. I am going to say this once and I want to be perfectly clear; there are no such things as automatic doors, there are just polite ninjas. Please give credit where credit is due.
