What Do I Make of This?

So, I walk into the bank yesterday to conduct some business. I walk up to the teller and in the course of taking care of some matters she asks to see my ID. I pull out my wallet and hold it up with the driver's license showing. On the other side of the fold is my badge. The lady takes one look at the badge and says "Oh, I knew you worked for the county, but you look like such a gentle man, I figured you were a teacher. You have to be mean some times to be a prosecutor."
