I don't answer the door most times they come to my house...

That being said, none of us would have a job without sales of one sort or the other. IMO, sales is one of the toughest jobs there is...especially if the poor sap has to deal with John & Jane Public.

In that regard, even though I may not care for their products, or even their primary methods, I try to remember to always be courteous to them should I have the misfortune of finding them on my doorstep.
