I always wonder how much a company actually saves with these machines. I used to be an attendant at self serve check out's in a grocery store and even though you get some people who know what they're doing most people are very slow. Granted fast food places probably save more since their ordering system isn't very complicated. Plus the more user friendly they make the ones at the grocery store the easier it becomes too steal so that's more lost money.
Do you know they aren't because of how much they suck at anything other than the self chechouts ? Like something as simple as pointing in the direction of the milk ? Because that's what happened in my old store when they started having the pop and chip companies stock their own stuff in order to cut down on grocery staff. It was so annoying when I would be trying to just get from one end of the store to the other to do my job, a job that wasn't even supposed to exist because the software was supposed to be able to handle everything on it's own mind you, and a customer would stop me every aisle to ask a question since there was no staff ever. I know realistically the attempts to replace staff will get better but they've so far all been such huge disappointments that ruined my days so I have no faith left.
