NYC is the home of the Jerky Boys. Sometimes, you have to go Jerky Boy on the sales people. Go back into the
shop and ask him the price of the
device and when he asks which one, reach over and grab the back of his head and smash his face against the counter (Be careful not to break the glass, you are trying to make a point, not be a vandal.) and say "That one! That one right there! And remember, whatever price you give me, you are taking 50% off that price and it comes with two free bottles of
juice, ya Jacknut!" It may seem harsh to people from the outside world (the "normals" as they call us), but that's just how they do things in NYC. If you don't do it, you are viewed as weak.
