Taking my car to a mechanic for the first time alone (21F). How do I avoid getting scammed?

Hey everyone! I’m 21 and I’ll be honest, i know absolutely nothing about cars. like, i barely know where the washer fluid goes lol. My 'check engine' light just came on and I’m terrified of walking into a shop and getting ripped off just because i clearly have no clue what’s going on.

What are some big "red flags" i should look for when talking to a mechanic?
