I was killing some time, walking between haircut and bookshop and BestBuy when I passed a car dealership. They had one I liked, so, after a suitable period of negotiation, I bought it.
Fortunately, I passed up they opportunity to drive the car first. The salesman took us for a drive instead. This was a clever move in retrospect. If I'd actually driven the car I wouldn't have bothered to haggle over the price.
After dinner, I went for a little rip down the 280 to Colma and bought a cheap laptop. Same color as the car.
Happy consumer, I.
