The Mother Of All Apologies, Part 2

I’m working the register on a busy sale day. A middle-aged man approaches me on my left and an elderly lady approaches me from the right. I call over the lady first but after she leaves:

Male Customer: *Angrily.* “I was here first.”

Later that day he flags me down on the food court.

Male Customer: “I wanted to apologize. If that was my mom, I would have welcomed you deferring to her over a younger guy.”

He went on to become one of my favorite customers.
