2. Be trustworthy

Recently, I became convinced that my car's brakes needed a complete overhaul: rotors, calipers, the works. And that's exactly what I told Victor as I handed him my keys. Imagine my surprise when he called to say my brakes were actually fine: the pads were still 50% at the front and 90% at the rear. He didn't try to sell me something, even when I announced I needed it.
