They have had very nasty first hand experiences with butthead farangs.
I no have problems with thai people
Pay respect, give kindness, accept the way of their mind, I am helpful, they give back me all. Yesterday I was stranded in the city center, át evening. The last songthaw has gone. I ask a motorcycle taxi man, how much the fare to the outskirt? 150, I ask softly, 120? He laughed, khun! the last red light junction is 10 kilometres from here, and your home are situated far beyond!
I laughed, said, yes khun. You are right, I accept the 150.
We drive home, in a nice mood. Say good farewell at destination.
