Putting menus on windshield wipers = solicitation?

I work at a restaurant and I was igned to spread menus around our area. I come upon a ghetto apartment, started putting menus on some cars, until two elderly females with nothing better to do than knit, blocking stairs with their thighs of cellulite and waiting for their inevitable death shouted "No! Uh-Uh (wags finger left and right)" at my attempt to place a menu on a car. I waited maybe 5 seconds to see what else I can dish out of their disrespectful communication. I responded with "Don't you have anything better to do?". One of the grannies replied, "I'm watching you! I'm preventing you from 'destroying' other cars and there's a sign up front that says 'no soliciting'. To ease the tension, I decided to stop and leave before their blood pressure rises or get a heart attack. My definition of soliciting is door-to-door selling candy bars, soliciting a minor to engage in ual activity... blah blah. I believe what I am doing is "advertising". Please give me your insight of "SOLICITATION". Sorry guys, trust me I'm the nicest guy on the planet. I'm just having a rough week.
