I used to feel the same way until I began focusing on my diet and purchased more produce. Self checkout is a nightmare for produce. They rarely have a bar code which leads to a mystical hunt through the usually horribly slow UI. Compare that to a person who has done it so many times they have the code memorized for your apples and they can just punch it in quickly and keep going. And don’t even get me started with how excruciatingly painful it is when suddenly all of the machines need assistance and the one attendant can’t be in 6 places at once.
