My family and I recently got back from holiday in America and Canada, and one thing I noticed in the shops is how little people seem to have in their bags. It might be because that's how the bagger (that's another thing, how come you can't pack your own stuff?) packs them, or some other reason. But over here I notice that people generally fill bags until they're almost breaking, especially myself. In America, people would often have loads of bags, each with few things in. It makes it a lot of hassle in extra trips to and from the car, and a lot of waste bags. I would stop the bagging guy from packing, just so I could use a sensible amount of bags.
