only home depot got that.
walmart is the next place should have self-check out..
most of people just grab couple of stuff and line up is crazy, that's why i gave up shopping in walmart.
when i was down south, Marysville, population like 25k there, middle of nowhere, their walmart has self-check out as well.
although by saying that, when i paid my liquor, cashier will pop up just to check ID, make sure i am 21 years old at least.
actually i would rather trust machine/computer than human being, because we human being can type number wrong and you just sign it without double check.
scanner probably never goes wrong.
when crisis strikes, there are always opportunities in the hood.
