Thais took offense to the act of kicking another Thai on the back while she was sitting facing away from him harmlessly. People in Asia took offense to being kicked like a dog because it denotes a lower status ( regard) of the person being kicked. I witnessed a scene in India while sitting in a car driven by an Indian friend visiting his huge home. He was driving me back to my hotel from his home where upon reaching his house gates which was a distance from his house, the gate did not open because the guard was snoozing ( maybe drunk? ) siting by the gate. Wordlessly he just emerged from the car , walked over to the guy and literally kicked him repeatedly like a dog. That, was a cultural eye opener for me.
