#4: Offer to return a shopping cart to the store for someone loading a car.

An and I went to Costco tonight to just look around. It was super cold and windy out and people were trying to be outside as little as possible. There was an older couple by us that had packed two carts full of stuff so I took one of the carts back inside for them so they wouldn't have to. (Someone else came up and took the other cart to use it.) This was an easy one to do, but that elderly couple seemed to really appreciate it!
