"Customer service to paint center. Customer service to paint center immediately! Customer is trying to mix his own paint!"

I happened to hear this broadcast over the public address system while I was wandering through the aisles at Wal-Mart yesterday. I stopped.

"Did he just say—?" asked the man next to me, a complete stranger.
"I think so, yes."
"Mix his own paint?"

Just when I thought I had heard it all.
