I am riding a subway train. Sitting across from me is an MTA employee with insignia which looks like this, except in gold.

I realize that this is the guy, whose job used to be to sit in a call center and give train directions to callers.

Somebody asks this guy for directions, and the MTA guy shows that person how to get somewhere.

When he is done, I ask him, if he hates giving directions to people after he was promoted to captain (now I realize that I was wrong about his rank, even though MTA personnel does not have ranks). He says that he does not mind, and still likes to help people find their way.

This must mean something, right? Subway, direction, promotion, helping people? Hmmmm.

I need to find some nice books about civil and military insignia.
