You've never dealt with some of the cretins we have in the US.

It's a tradeoff between space vs. time. If square footage is cheap, you can add more lines until there are enough that even with your guaranteed cretin blockage there will always be a line open. If square footage is expensive, then having cashiers to manhandle the cretins is more productive.

What's interesting, is that Land here in Singapore isn't precisely cheap - but all the fair price stores that I frequent have automated kiosks. Particularly if you have Apple Pay (or "Pay Wave") as they call it here, if you have just a few items, you can scan, bag, pay in under 60 seconds. It's pretty awesome.
