That awkward moment when a customer asks me to look at some great used car they own immediately after they bought it, and I have to gently tell them they bought a worn out piece.

That awkward moment after some customer, co-worker, or who ever asks me what my religion is, I say I'm atheist, they pause and say something like, "Oh, I'm sorry to hear that." and I have to respond with, "It's a point of view, not a terminal disease."
