In the supermarket

So, I had just put my stuff on the conveyor belt at the checkout and was
waiting for the person in front to be processed when a woman came up
behind me. Before getting out her stuff, she started looking around. I
asked her what she was looking for and it was the blue plastic dividers
you put to separate your purchases from everyone else's. I had already
put the only spare one on the belt behind my stuff, ready for the next
customer. She finally spotted it. "Oh, sorry," she said. "Most men
don't do that."

Well, I'm not most men.
