yes they do but as i said, irl this is what it's really like....sometimes it's like being in a war and i did once get pushed over getting in the way of shoplifters.......they are mostly not desperate people looking for stuff to eat you know. Plus if you add on the sizable amount of the public that treat us like shit on their shoe, are aggressive, rude and abusive you might understand why i have a rather jaded view on this. Self scans are only going to increase, we all know why and it's now a fait accompli as they are squeezing down staff levels so much that it's going to be the only thing that eases the pressure on myself and my colleagues
