When I used to work at a health food store, I had this sweet older lady come up to me with a newspaper clipping clutched to her chest. She said, "I want to ask you if you have something, but I don't want to say the name, and I don't want you to say the name, either!"
And then she showed me an advert for a bath salt mix we had, called "Tired Old Ass Soak." XD
Sometimes the elderly encounters are the best in a grocery store. :D
