Once in Cambodia, I encountered an old man who chilled me to the core, a thousand-yard stare, and no reason but complicity for still being alive.
I had rented a bike in Phnom Penh years ago, and sat at a restaurant across from my hotel the next morning watching as a couple guys came with a key and drove it away from the hotel parking.
A friend and I followed and watched them drive it behind the shop I rented from. It was just a couple of blocks away
When we walked into the shop from the front and asked what was going on, they denied they had the bike until we walked around back, and there it was. A very tense set of conversations ensued.
There was a skinny old man in a sarong on a sleeping platform in the middle of the shop with a shaved head who barked instructions and glared daggers at us as they gave my passport back,
The dude was evil incarnate. I can still picture him nearly 20 years later,
