LA metro has a stage below them called "ambassadors" who walk around with ipads, presumably to help people navigate the system and also call for maintenance or security should there be a need. From what I can gleam they are paid $25/hr.

From what I know of LA metro, most people ignore the ambassadors.

		Well that would be hard to do considering they will call the police on you should it merit it.
