Last week I was back at the only store in town (that I know of) that sells the brand of yarn that I use.
I didn't use a shopping cart and picked up five skeins of yarn, tucking one under my right arm.
When I reached the cashier, I put four skeins on the moving counter and reached for money in my wallet. She checked me out, put the yarn in a sack and gave me change. All of a sudden I realized I had another skein under my arm! She hadn't seen it and I don't know where my mind was.
I apologized and she said no problem and rang it up. We both laughed; me a little nervously?
I really was not trying to get out with a free hank of yarn.
