Every customer that walks in the door is going to be mad that their car is broken, and expect you to be a mechanic and know how to fix it. Spoiler alert: They hire cashiers, not mechanics or technicians
The entire business is built on selling car parts cheap because they don't have to pay for mechanics or ASE certifications, and if you DO have a parts certification, you get no bonus pay for it. Once long ago they had programs for getting an ASE parts certification but they have long since axed it as the cost has exceeded the need of just selling parts, as advice does not bring in any money.
If you think the company hiring people who are clueless as to how cars work to sell car parts is bad, wait until you get to the corporate side where they never press charges for thieves, have a logistics train that involves routes that change twice a year, an inventory management SO BAD that the STANDARD PROTOCOL is to call a store that says something is in inventory, and ask them to check in person because it is extremely often that the part was never stocked despite being in the computer's inventory.
I have seen everyone who has even the slightest inkling of what makes a car run, what problems are typical of what symptoms, or even people who know the difference between brake fluid and power steering fluid is, are all leaving the company in droves because other companies will pay them for their knowledge and certifications, and rightly so.
