The unpredictability of knocking on the door of a stranger can be a scary bitch. I have had several people snap on me over the years at the health dept... Never pulled a weapon on me, but enough to make me start looking for an escape route. We weren't allowed to carry a weapon for protection either which is bullshit. It's just not right that you put your own safety on the line, as well as the well being of your family, just doing part of your everyday job. It's truly ridiculous. But shit, you have to bring home that bacon somehow right? Be safe out there man.
