...but when I do, I take it back.
A few weeks ago, I bought a couple boxes of granola. At least I thought I had bought some granola, until I wanted to open a box and have some for breakfast. And then I could not find that granola anywhere. I checked the shelf I normally put cereal on; I checked the top shelf where I store the extra cereal when I have too much for the regular shelf; and then I checked again. Then I checked my van, just in case I had somehow left a bag in there. And I checked again. No granola. It just was not in my house.
I started wondering if I had actually bought the granola, or maybe I just thought about buying it and then decided against it. Then I dug out my receipt and checked. Yep, I definitely bought granola.
So I called the store - even though it had been almost two weeks - just to see if perhaps they kept a record of any items left behind at the registers. Nope, no record. They keep things for about a week and then put them back. But, Kyle said that wasn't a problem, and they'd be happy to replace my two boxes of granola. So I wrote his name on the top of my receipt, and finally got back to the store about a week later. They were indeed happy to give me two new boxes of granola to replace the two I couldn't find. No questions asked.
I took my new boxes home and placed them in my cabinet. Then a few days later I moved some oatmeal boxes - and found my original boxes of granola behind them.
Which means next time I was out, I took those replacement boxes back to the store. The lady behind the customer service desk just smiled.
