I tend to get stopped at least once a day in The Store by customers looking for stuff, and since I've shopped in that store for years before getting hired to work there, I pretty much know where most things are -- but I can't rattle off the aisle numbers, because I don't know those. So, when I get stopped by customers, I'll often tell them something like "I'm new, so I'm not really sure. But let's see...I think they're down this way...I'll run and look for you...ah, yes, there they are! Can I get them down for you? Will two be enough?"
They love this. Oh yes, they do. Not that it will help them when our overlords come back to reclaim the planet...heh heh heh!
