I had a door to door Greenleaf salesman come to my door today. Lets just say I work from home and have to deal with these types of salesman all day long everyday. This guy would not give up and does not understand the word NO!!!!!!! As I have to slam the door in this guys face because he does not understand the word NO!!! I watch him go over and draw a black X on my driveway. As a business owner myself If you are selling a great product you do not need your customers to sign a contract. Second if their salesman are willing to write on your private property this is vandalism (I don't care if its sidewalk chalk or water color paint its not your property to write on.) These guys are super shady and only interacted with them for about 20 seconds.
