Our local supermarket has 4 self scans open all the time and normally two cashiers during the day, and three or for on a weekend or evening. Keep demanding more more and watch more self checkouts get installed, why pay four cashiers $15/hr when you can pay one to run 4-5 lases.
I LOVE the self check out at the supermarket, the ONLY problem is if you have produce codes and scales are not provided!!!!!
I hate self checkouts and refuse to use them. They always mess up on me and I gave up on them long ago.
I've been on clerk-attended lines at the supermarkets and have the clerk who runs those banks of four come up and say I can use one of them instead of waiting. I tell 'em I'm not for putting people more out of work and get the "Well, you'll put me out of work" reply - or more often - rolleyes. I tell the first that they put three other people out of work. I'll do that even if I have only one item, just to be cranky, as these self-checkers are an obvious we-dump-our-costs-on-you technique, IMO.
I can see the self-checks for one or two items when there are long lines at the regular checkouts, but when I see people scanning item after item, like 20-30, I have to shake my head. All they are doing is giving management free labor.
