Did the original thread mention the TV series House as a context? After a scene that had House talking in a typically unsympathetic way to a patient who made a mess of some kind (I forget the details, but bowels may have been involved), House left the room shouting to the nursing staff 'Cleanup on aisle three" [I think it was 3; there are no doubt web-sites where someone will check. ]
The reference was to a supermarket, when a customer drops a bottle and it smashes. A supervisor shouts 'Cleanup on aisle N' [large shops are often organized/sign-posted by aisle]. House cared as much - this was the point.
