Waitress gave me the Seniors' Discount without asking. I'm still quite a few years from actually being a Senior, although my arthritis and my white hairs disagree. I sat there staring at it for a while, thinking, "Should I be insulted, or should I just be happy to save $3.80?"
In the end I made the sensible choice, said nothing and saved $3.80. Now that the reality has sunk in, though, I really want to cry.
