What's with the grocery stores?

They have those cool little 2 tier carts to zip though the store with, but hide them waaaaayyyyy back in the corner. (Then there are those monster carts that look like trucks for the kids - we won't go there.)

And... they have ALL THOSE CHECKOUTS, and two are actually open. So, you try to use the self-checkouts, only to find half are out of order. And the line stretches to aisle 10.
