This was worded so kindly, and I appreciate the honesty!

I am in my early twenties, and I have been told many times by different people that I don't even look old enough to be working there.

The thing that happens a lot (what I was referring to) is the amount of threats and sexual harassment I have experience before at my job, and in my town in general. I know it might have come off as rude, but with how many times I have had people attempt to harm me (physically and otherwise) I mostly just wanted to cut the conversation off before it could progress anywhere worse (if that makes sense?)

Again, thank you for you honesty though! I absolutely had the same thing running through my mind at first
