Women with small children who can't take that extra 30 seconds to roll their freaking shopping cart over to the cart corral.
This woman was parked right beside me yesterday as I unloaded my 1 bag and then returned my cart - she unloaded and started heading toward the corral (I thought she was watching me and saw how to do it) - and then she pulled a U turn and pushed her cart up into the landscape island. I pulled out and took this photo before leaving.
