For lack of a better word I worked as a dealer walking around crowded places where there's flow of people, finding new patients for my physician. It was difficult since people had to sign some papers and change their physician on the spot. I personally would never sign such thing on the street, but to my surprise cca 4 people per day or one in one hundred did. I met with some hostility, but after I got used to it it was a great experience and definitely worth it despite the low pay. My conversation skills have improved greatly.
Edit: It was a new physician with good reputation so far that I visit myself to this day. Half of the people who signed up just turned 18 and didn't have any physician and the rest just moved to the area. Also, if my writing is incoherent, it's possibly because English is not my first language.
