I and others I know that talk about this were bothered by this long before we worked retail. And it's a mental irritant in other places too. I strongly exaggerate on my resume and say I'm detail oriented but the truth is I see the flaws in the patterns of workplace practices, just like everyone else does, but I take the time to investigate the flaw instead of ignoring it, and nearly always it's something that has gone wrong and needs fixing.
People see, people notice, people are irritated by oddities and flaws in patterning. And that's why I can't see how a "quick" zone can be done. It's either done to completion or it's not a zone at all, just a few collections in a sea of chaos.
