Whenever anyone comes to my door (obviously not a local child/teen) selling mags, books, siding, etc., I ask them if I could see their permit to sell. Shuts them up and usually gets the bunch of them scattered around the street to hop in a van and drive off.
One time a man tried to give me a 2 liter bottle of soda. I guess to start the sales pitch. I said "Ah, no thank you, where is your permit?", went to shut the door and he stopped me! I was terrified! I then became angry and whistled for my dog, who is huge, but harmless. Dog came running and I told the salesman that he bites and to get his hand off of my door. NOW! I slammed it so hard and then called the police.
I hate pushy people! How dare he try to stop me from closing my own door!!!!!
