I never use self-checkout machines. For one thing, it's a lot more work for me, scanning codes and packing items into my bags. For another, I enjoy the conversations I have with the tellers.
In the U.S., yes. If they don't have enough staff on hand to specifically bag, then the cashier will bag it. Some places (Meijer, for example) will have a carousel of bags, and the cashier bags things as they are scanned. When one bag is full, it is turned so you can pick it up and put it in your cart while the cashier continues scanning and bagging. The only place I know of that won't bag your items for you is Aldi, but I'm sure there are others; it's just not common to have to bag your own items, unless in self checkout.
