There are benefits to self-checkout not mentioned in the article. Space. This is probably not an issue in many countries but for example in Switzerland where space is limited in many stores this makes a huge difference. You can have double or triple the checkout points than if you had regular checkouts. I have seen optimized regular checkouts (no conveyor belts) in super markets now as well but they still require double the space than a self checkout. Generally I also only see 1 attendant for 10 or so self-checkout machines. They carry a special phone which lets them deal with age checks or random inspections. In some places the random inspection can even be done without the attendant (the attendant can release the register to allow you to follow the steps yourself.).
