Sometimes I think this is the way that all Thai boys view farang.
To them, we're all rich and spoiled with pampered lifestyles to begin with. And the fact that we give them so much money (in their terms) for receiving so little in a return (a one hour roll in the hay) makes us a bit naïve and gullible in their eyes as well.
In their eyes, they're not the ones who need financial advice - WE are.
