I stopped at a pawn shop the other day and noticed they had several shelves full of various sockets. All except for one size.I was at one of our storage facilities the other day, helping a manager change latches on a storage unit, a process which required a socket set and ratchet.
She picked up the socket set (dual metric/inch of course) not realizing that the lid wasn’t latched and accidentally dumped them all over the golf cart and the ground.
I leave it to the reader as an exercise to determine which was the only socket we could not find
