Exactly . They better have thick skins and fast legs.

When I was a kid, I had to sell chocolates door-to-door to pay for the fees required to play little league. I was probably 8 years old at the time. At one house I knocked on the door and an angry guy came out and asked me what does that sign say while pointing at a "no soliciting" sticker on his front screen door. I replied "no soliciting." He slammed the door and I was confused. I must have knocked on another hundred doors after that and a dozen doors with signs like that. Some of the people with those signs even bought the chocolates. After I got home I asked my mom what soliciting was and realized what I had done. None of those people with the sign thought to explain it to me and my parents didn't warn me before I set out. I still laugh when I see those signs.
