BTW - with a new set I always enter the aisle, slowly caress the gondola, and whisper, "hey there my friend. I'm here to give you a nice gentle reset.". I find I have no surprises after such as needing to scrounge around for additional shelves or hammer at bent bent brackets to make them fit. A nice touch on the gondola's shoulder and a polite word seems to get them in a good mood thus allowing for a smooth reset.
