I live and work in CG and the meter maids have made my life (and my employees) miserable. They target specific people and businesses, come around and wait till time about to expire then yell or aggressively state you are not allowed to put money in when they are there (hello?! you have to feed the meter when it expires, if they happen to be coming or waiting around, that is not my fault or problem!)
The City is inconsistent at best. They bother people like you that work here, but on some streets (like where I live) they dont bother to control traffic, speeding (me and neighbors have asked numerous times and have almost been hit more than once by flying by cars), or even parking for a part of the street where there are commercial / retail properties. Funny how some (large companies or possibly homeowners who are favored) get away w/ things while other individuals or small guys are treated badly.
The mayor, whom many of my co-workers have contacted, passes the ball to the parking director, who's answer is always to protect the meter maid! interesting since they are city employees, and I pay taxes, but my voice is not heard!!
