Stores used to pay people to wrangle the shopping carts and keep them stocked at the cart stalls. Now they have trained you to manage the carts yourself for free. They also trained you to check and bag your own groceries at the self checkouts. What you might see as responsible behavior is actually just cost savings to the store and you were manipulated into working for free so they didn't have to pay an employee to do those things. In a homogenous White society being responsible for your shopping cart is a great thing. We don't live in a homogenous White society so think about that when you are doing some nigger's job.
