There was a lot going on there with the guy returning to the store and coming out with a manager. All the while you're in a checkout line buying paper towels? At Costco? Never go to Costco to buy one or two everyday items. Get them at the neighborhood store, pay a little more, and get the 24 roll pack from Costco on Saturday!
I'm just giving you a hard time, of course. I think your wife was pretty bold. She should have called your cell, assuming you had it, and told you to get out there!
