I went with a buddy to a sears counter to exchange a broken speed wrench. My friend walked up to the counter, laid the wrench down and grunted. The guy behind the counter picked it up... examined it... raised his eyebrowns and grunted too. He walked over to the display, picked up a new one, handed it to my friend and grunted again. After an approving grunt from my buddy we were on our way.
It was very "Tim the tool man Taylor" in there for a minute, but the wrench was replaced (literally) without a word.
