And the flip side is consumers who don't listen, cuz they know it all.
Phonecon early Sunday morning, in HD (I worked hardware there for a hot minute) --
Him - "The nail gun I bought yesterday doesn't work. I loaded it with the correct nails according to the instructions and it won't fire"
(After getting the info on what nail gun it was) --
Me "Ok sir, what type of compressor do you have it hooked up too?"
pause, pause, pause - crickets
"Compressor??? I need a compressor???"
"Yes sir, that's a pneumatic nail gun, says so on the box. It needs an air compressor to work. If you need one, we have several on sale. Failing that, we have several nail guns that work off of gas cartridges. Either way, we can square you away."
"Ok, thanks" click
What I didn't tell him to do was blow really really hard on the air fitting and pull the trigger and see if that would work. Wanted to though.
