Emergency Services Regular

If a character has a history of problems, someone from Emergency Services is likely to help out to the point of getting to know the character. This could be either somebody from the police, firefighters, paramedics, or another emergency group. It can happen to the point where someone like a police officer would simply say, "Here we go again". However, this can also happen if the character works for the Emergency Services, since many services will send a person who knows about the situation when possible. This situation can also apply in a school setting, as schools can have their own set of services.

Real Life

 * In places where community policing exists, local police get to know the people in their communities.
 * Quite commonly noticed among emergency room personnel, more among those that can't afford care than those injury prone. Problem is most of the regulars don't realize the same people keep treating them. Many of them are (often belligerent) drunks and not particularly well liked by those who have to deal with them.
