The only negative thing I've encountered with self check out is when the store gets busy, you always have 3 of the 6 checkout stands being stonewalled by people staring blankly into the screen, frozen and unable to figure out what to do next, and then there is always one pushy guy a few people behind you who keeps bouncing around ready to run ahead of the entire line because we are all "wasting" his time unnecessarily by not bum rushing the slowpokes.
But besides that, on slow days, I prefer them.
