Over the years I've found that when I'm considering buying something from someone, if they're trying to distract me from what I'm there for, they're hiding something and trying to get me to overlook it. Their goal is to make their problem my problem. The bigger and flashier the distraction, the bigger and more annoying the problem.
I don't calmly walk away from such situations. I immediately vacate the premisis with such vigor that light continues to bounce off the place I was previously standing because it doesn't realize I've already left. When the light finally catches on, my image is doppler shifted deep into the infrared.
Pointy shoes..I wonder how they would react to me taking a 3/8" diameter steel rod then banging it with a hammer against their wing walk?
