There’s nothing worse than stepping foot into an auto mechanic’s shop and feeling like everyone is speaking a different language. For that matter, there’s nothing worse than feeling like everyone is speaking a different language no matter WHERE you are! But knowledge is power, and you can feel totally in the know and in control by just learning a few key terms and slang words that get throw around the auto shop.
