I'm going to put on my best face and try to make some sales today." I thought to myself, as I knocked on the first door in a long line of potential customers. After a few moments I heard the noise of latches and the door opened slowly, revealing behind it a beautiful girl smiling at me. I gulped, and tried to regain my composure.
"Hi, Can I help you?" she asked.
I went in to salesman mode, "Well, the real question is: Can I help you? I'm selling these amazing deluxe vacuums. If you could just spare 2 minutes of your time I could give you a demonstration. They have an assortment of incredible features that will facilitate all your cleaning needs."
"Really? Well, I wouldn't normally be interested but why don't you come in and show me how you can facilitate my needs."
