I had to get a bucket of trichlor pucks the other day. Standing in front of the shelves I pondered whether I wanted the smallest size or one size up when one of the salespeople came over.

"If you're considering this size," he said, pointing at the 25# bucket, "take a look at this one, instead. It's a much better deal."

"50 pounds of trichlor?" I shook my head. "That would last me 10 years! I use bleach."

His face fell. "Oh," he said, and walked away.

Nothing to sell here, poor guy.
