It just look like loud blaming and raging than any kind of physical clash.The tourist looks enraged with an unread person and perhaps got misconceived or something. People didn't engage in the dispute right on as they are deemed guest in any touristic place of Nepal and usually get the benefits of good treatments from the locals. It look as if,it's his lucky day to get away in such a good fashion;had he been engaged with late night,charged up urchins in that way,he would have found himself in a nearby medical,after all guests are gods or something!
