I hate that too....I just open the door and if it's obvious they are soliciting i say "I'M NOT INTERESTED" and shut the door in their face. I also despise phone spam! once some...some....phone spam loser called and I knew right away they were spamming because they asked for "Mr. or Mrs. Roberts" I asked 'who's calling?' and they said "blah blah from XYZ company we'd like to offer" I cut the twit off "Sorry, I'm not interested, take us off your phone list" He/she said "Are you Mrs. Roberts, you don't sound old enough" or something. I FREAKED RIGHT OUT!!! " I SAID we are NOT INTERESTED and take us OFF your phone list before I file a phone harassment complaint!" He had the audacity to ask me my age.....ohhhh boy I was sooooooooooo mad.
