I didn't know the 4-square bit was still in play. Last I ever saw of it was over a decade ago. My GF and I were shopping for a her a car and as soon as the salesman flipped over a printed form so he could draw the 4-square lines on the back, I nudged my GF and said "Now, here he goes with the 4-square thing...". The salesman stopped dead in his tracks and we exchanged poker faces for about 5 seconds while he flipped the paper back over and we continued where we left off. The thing is, I really didn't even fully understand what it all was about. I just knew that I didn't like all those different numbers being thrown around so quickly and fancily and I wanted to deal with just one number- the selling price. I guess, to that salesman, my comment made me sound like I was one of "those customers" that knew the game and there was no sense in wasting his time. I got such a good deal on that car that an ex-girlfriend from years prior contacted me outta the blue about it. It turned out she handled the finances at the dealership's main branch and the low selling price for such a rare/uniquely-equipped car caught her attention, then she saw my name on the paperwork.
