Kinda funny Sears- Craftsman story. Long time ago, I needed to swap belts on a Cummins 1710 on an Onan generator set. I needed a 1 1/2" box wrench with some crazy offset. A guy that worked for us had a 3/4" drive Craftsman set and said I could slice a section off his 1 1/2" socket to build the wrench if I got him a new one. I agreed, sliced the socket, welded a handle to it in the required offset and went and did the job.
The next day, my brother took the remainder of the socket to the closest Sears and showed it to the guy in the tool department. He said I need a socket like this. Guy went and got it and said ok, see you later. My brother said no, we cut this in a saw. I'll pay you for the new one. Guy said no, this is fine.
On the Snap On thing, I wrenched on diesels professionally for almost twenty years. I always used the correct tool for any given task. I can count the amount of times on one hand I needed a broken tool warrantied but our Snap On guy always did it, no questions, as long as there weren't marks from a pipe of any hokey type of extender.
One time, I bought their fancy double flaring tool. The cone part didn't spin freely and it would ruin the flares. I gave it to him and he gave me a different one that worked fine and I still have today. Only problem was he took mine and put it on the shelf for someone else to buy. Whatever.
Another time, I bought a soldering gun packaged as Snap On but made by Weller. Something was wrong with it so he exchanged it. Can't remember what exactly as it was a long time ago but we went through a few of them before we got one that was right AND the box wasn't cracked. Still have that today as well.
The Snap On guy probably bent over backwards for us because we spent silly money on that truck.
