But many thais go off to the border and play in them in Poipet, its been that way for decades. Many thais go to work there too because of it. They might as well give into demand and profit from it.
I don't think so, I have to coordinate with others and children want to play. So unless they have content on youtube and a website I don't see why I should.
They aren't usually bothered these days. I think once I was asked to show proof of onwards travel and I said I was going to Singapore by train but you had to buy the tickets at the station, and they just waived me through.
