Here in the UK you have to pack your own groceries which can be annoying as some people are really slow at packing or their kids are wanting attention which also causes delays. If you use the self serve aisle something always goes wrong and you have to wait for an attendant to check the issue before you can process the next item, with the self serve machine you have to scan every item individually the put it into the bagging area because you can get an unexpected item in the bagging area warning message as it’s all base on the weight of your groceries.
it can be really annoying using a self service checkout for this reason.
All stores now charge for plastic bags although some are not selling them either making you bring your own bags, but they are still happy to use plastic on your fruit and veg.
All supermarkets have an in store deli, butcher and fish counter, some make pizzas, sushi and also have a bakery.
