I was with a friend once who was buying a bunch of demasoni from petsmart. They were on sale for some ridiculous price. After going round and round over the whole "you cant add so many at once" speil, he asked her to bag up the two Demasoni that slipped into the "assorted african" tank adjacent to it. She insisted that they weren't demasoni and were "assorted african cichlids" and therefore not compatible. He persisted and she finally agreed to sell them, but refused to price them at the Demasoni price, and used the "assorted african" price instead....which at the time was much higher. This was a brutal case of someone who just doesn't get ANYTHING you're trying to explain, and does not want to.
I've seen this a few times at petsmart with their tank system, tiny fish can fit right through their slotted dividers.
