Let me tell you a short story. One fine day, a bus driver went to the bus garage, started his bus, and drove off along the route. As usual a few people got on, a few got off, and things went generally well. At the next stop, however, a big hulk of a guy got on. Six feet eight, built like a wrestler, arms hanging down to the ground. He glared at the driver and said, "Big John doesn't pay!" and sat down at the back.
The driver was five feet three, thin, and basically meek? Naturally, he didn't argue with Big John, but he wasn't happy about it. The next day the same thing happened - Big John got on again, made a show of refusing to pay, and sat down. And the next day, and the next.
