Someone recently asked online "If you’ve got a full cart and someone behind you has just 2 items, do you let them go first?" My response: I don't know if that ever happened to me. But they never do for me. They look like their buying the whole store sometimes, but they won't let me go with my one or two items sometimes. The other day I had just a couple of items, and again looked like a lady was buying the whole store. And a cashier said she'll take the next person in line. That was me, but the lady buying the whole store actually took cuts and rushed in front of me. She did.
