The guy is remarkably stupid. His intentions were obviously to watch or have sex with the individuals in his hotel room. Obviously some kinky fantasy that’s being playing around in his mind. It appears his imagination got carried away and never considered being disabled, or mute, might have implications of his gratification. To trust individuals you picked in the street is never gonna end well.
Now he’s paid the price, learnt a valuable lesson about Thai hookers and humiliated himself and become a laughing stock on the worlds stage. Not the happy ending he expected!
