Last night, someone just like him was indeed robbed. Anyone seeing someone standing under the streetlight at the alleyway's entrance, counting a thick wad of cash, would be tempted by the thought, "How great it would be if that money were mine." Some people, constrained by their moral compass and the law's threat, would keep such thoughts to themselves and pass by quietly.
But others, accustomed to ignoring the law's deterrents, would turn those thoughts into reality.
Thus, a stylish individual in a purple unisex suit was dragged into the alley by several thugs, who gave him a not so friendly "greeting" and took the money that didn't belong to them.
For these people, this was probably a trivial matter. They had already memorized the names of those they couldn't offend, people they'd never forget for the rest of their lives. Obviously, the guy counting cash wasn't one of those people, so they felt no pressure.
