"Hi, I'm The Sign Guy."
For quite some time i was one the guys responsible for illegally installing 200-400 promotional signs on people's property throughout the city (aka street spamming) while i simultaneously monitored 15 "signwalkers" spread out within proximity at various big intersections and freeway off-ramps. A signwalker is a person who is standing on a street corner holding a 10 ft. sign that will direct traffic to the sale we're promoting that particular weekend.
You have to understand, normal people do not signwalk. Ask yourself if YOU would do it? Probably not. It appealed mostly to either kids under 16, the homeless, the drug addicted, parolees, halfway-housers, people on unemployment or disability trying to cheat the system, and those who insisted on working where they can chain smoke or dance all day long. It meant a lot of firing and hiring, and finding people on the spot when someone wound up arrested, drunk, missing, or just didn't show up to begin with.
