right, you can pay someone with certs $15+ an hour to do for the most part what a kid will do for minimum wage and be happy about it. it’s business. people like what are on this forum are a minority. i would imagine your average autozone customer needs replacement bulbs and fluids.
i don’t ever have a problem there because i get info from trusted sources and i just go there if they carry the part i need. i tell them and if they ask questions i politely answer and casually decline any arguments. in and out in 5 minutes.
edit: i am sure there are some very knowledgable employees there. the run of the mill employees that i usually run into though don’t know too much past routine maintenance though.
