I do that often do--then if the parts turn out to be wrong,they can blame ME instead of the other way around!..
One day long ago at an Autozone I was waiting in line to get waited on..
I heard the guy in front of me ask for a "complete tune up for a Chevette,you know,plugs,wires,cap,rotor..."..the kid at the counter looked like he'd been there maybe 3 or 4 days..did his best though..got the computer to list the car,and show the tune up parts...then he asked the customer "is that a gas or diesel engine?"..
The guy sighed,and walked away,and said "never mind!"...

....
I was next--all I wanted was wiper blades for the caravan,one flew off on the highway and I had to buy another one,and of course there was no chart to tell you what size,at the blade display...
I told the kid what year and model it was,asked what size do I need?..the kid starts asking "is it delay wipers?..you want the rear wiper or front?...do you want winter blades or summer type"?"or refills?"...."is it"......I cut him off before he said another word,and I pointed to the listings on the computer ,and I said "I asked what SIZE it takes,thats ALL!.."look--ALL the listings end with "16",so they are 16"..thats all I needed to know!..
OH!"....16"..

...THANK YOU!..
You know what scares me now about these stores..they let these people plug in a scanner to tell you whats wrong with the car..

...its a great way to sell expensive,non-returnable electrical parts!..so what if it failed to fix the problem and shut off that pesky CEL..(cash eliminator light)..its not our fault!..

..
My friend told me the other day while he was buying oil at Autozone,a woman came in and said to one of the kids behind the counter "remember me?--you sold me the rear view window glue awhile ago!--well,I goofed and glued that metal thing on backwards,now what do I do?..
The kid says "Oh,I cant take care of that for you"..and he reaches under the counter and grabs a large pair of vise grips,and heads out the door with the woman leading the way...when the manager who was getting the oil filter for my friend came back to the counter,he says "hey--that new kid?--he just went outside to take the rear view mirror button off that ladys car with vise grips!"...
His face turned white,and he runs outside screaming "WAIT--WAIT"--"Dont take that thing off like---"...too late!--the kid has it in the vise grips already.and he's like "what"????....."It came right off dude!--no problem!"..

...The manager proceeds to ream him out for risking busting her windsheild and he just let it go in one ear and out the other...
..He didn't last long there..
