Depends on the supermarket I suppose. A few times a year I go to a rural-ish supermarket in the US (town of maybe 5K people) and it's very old-school, the check-out people are very nice and gregarious, the baggers bag with great skill, etc.

I certainly hope the poor folks who toil at Aldi or Safeway might find a better thing to do with their lives, and if those stores are displaced I won't be too sad.
