So I went here today and a tall white short hair guy was there and I ask him if auto-zone did spark plug changes, and in a mild-rude way he said WHAT? I repeated "do you guys do spark plug change? And again he said "can you say that again?" Then again I asked and the next thing he says is "I don't know what change is". I was about to just turn around and leave the store but I didn't want to be rude so I told him "You know, you remove the old spark plugs and install the new ones" then he finally understood me. At that point I wanted to leave the store but I asked him if he had any E3 ones which I know auto-zone doesn't carry just so I could leave in a polite way. I'm Hispanic myself but also a U.S. Citizen and I work with a lot of clients developing high-end websites and I never had an issue of this sort when talking to them nor anybody in English. I love AutoZone but I will not be coming back to this one so that the employees will give me a hard time He knew from the beginning what I was asking about. read more
