Drinking with the locals in Luang Prabang

This is how it works - many bottles of beer, one glass, fill the glass with beer, pass to your neighbour on the left, they "down in one" or in Loas "100%", refill the glass with beerlao and pass it on.
fun, my kind of game ....
but they said I was a lightweight as i wasn't doing the 100% thingy, yikkes ....
will practice ! goodie
