I remember going door-to-door when I helped my dad; we were canvassing for a vacuum company. I recall helping him give out flyers for our products and I remember going into people's homes with my dad when he was pithing and doing presentations about our products to potential customers. However, I would join my dad when he went to see people and go into their appointments to see them, if he had appointments to go see them, if I remember correctly. I think that was the usual case. We might have been invited into people's homes if they wanted to see our products when we were canvassing but I don't recall for certain. This was back in the '90s.
