They may just make do with fewer employees then. All Kroger stores around here(Metro Detroit Area) have self-checkout lanes and maybe 2 cashiers. Another chain, Meyers has three times as many self-checkout lanes as Kroger already. More chain stores and even independents will probably use self-checkout lanes. These can also be modified for other retail businesses. I’ve seen them at Home Depot or Lowes, can’t recall which.
In VA and WV, both Lowes and Home Despot have self-checkout lanes.
Home depot has the self checkouts. I believe Lowes is considering it, at least the one in Marquette, MI. I was in Flint Michigan and i had no choice but had to utilize the self checkout at Meijers. i got so disgusted with the damn thing, half the items would not ring up. just said forget it and walked out of the store.
