Oh, I just remembered another time!
I'd just done my shopping, with two preschoolers in tow, and I stopped by the coin machines to purchase a small toy for them. I put my grocery bags down by my feet, so I could fish out change. When I looked down again, my bags were gone. Vanished!
I said, aloud, "Someone just took my groceries!"
The cashier said, "What? Just now?"
We looked around, but there was no one in sight. She asked, "What did you have in your bag? Who was your cashier?"
I told her - a loaf of bread, a few other things. No receipt - it'd been in the bag. She said, "Wait here," and went and consulted with the other cashier. Then they replaced all my groceries, free of charge!
I love that store.
I've been shopping with them for 20 years, through a change of ownership and name.
