Bring Your Own

Usually I write about the funny things my kids do. I think spending so much time with my kids this summer, is causing their behavior to wear off on me.
Yesterday I went to the grocery store. I needed to buy milk and bread. I got a few other things. I put everything on the belt at the checkout. Then I put my green cloth bag in front of my groceries. I noticed that it wasn't empty. There was something inside. I opened it. It was garlic.
I had bought garlic earlier in the week. I used the last of it when I made spaghetti. I don't use garlic every day so I didn't need it right away. I guess when I emptied the bag, I took everything else out of the bag and since the garlic was small and light I didn't notice it in the bottom of my bag. So now I was at the check out with my stowaway garlic that I had bought earlier in the week. I didn't want to attempt to explain to the checker why I had brought my own garlic to the store.
Can you imagine? "I uh brought my own garlic with me because I wanted it to see the world and know what it was like at other grocery stores." So I just put it on the belt with the rest of my groceries. For $0.50 it was worth my dignity. Except that I had purchased it at different grocery store and the produce bag was slightly different than the store I was currently in. I'm sure the checker snickered when she rang up the garlic. Luckily she didn't question me. I was so embarrassed I couldn't even look at her.
As soon as I got home, I made sure that the garlic was put away safely with the onions.
Am I the only who does things like this?
Does any else take garlic on field trips and bring garlic to the store with them so they can pay for it again?
