I agree! I hate self checkouts. I will not use them if I can avoid it.
I used to use some of the ones at Walmart, but, since they've renovated the store and taken away the long conveyer belts at the self-serve checkouts, I've quit doing so. I used to be able to load my cart on the conveyer and then check myself out. Now, I have to take one item at a time from the cart, scan it, and then try to figure out a way to sit a cartload of items on the floor until I get an empty cart to put them in. That sucks wet mud-turtles.
If food is cheap and good—I will self check out—they will need the money for armed guards to prevent shoplifting.
