I think it's possible that you are underscoring the theme in this thread of people not observing written communication in stores. I'll bet you a can of pumpkin pie filling that if you look next time you go, you'll see numbers on the aisles.

Supermarkets, and many other stores as well, want you to walk all over. That is one of the reasons they re-arrange stuff from time-to-time.

Walk into his store with a "Help Wanted" flyer taped to your back.

I've never seen a supermarket that did not have numbers on it's aisles. A long, long time ago, some didn't have signs saying what was in a particular aisle, but even then, they had numbers.
