The days of turning a blind eye to foreigners antics have already come to an end,

I think that was still going on a little around 2010 in some places but you are right that seems to have mostly disappeared over the last 5 years - at least that I'm aware of. I suppose it might be going on in secret or behind closed doors somewhere. But the local laowai bar bustling nightly with the party kings out hooting and having 'stare-downs' with locals and boasting about how easily they can get weed... well that does seem to have disappeared.

btw - Im not a downer, I'm for a fun good time, I get why people need to 'blow off steam' but yes it always boggled my mind that these types think China is a good place to do this kind of thing. When it gets into 'raves' and drugs and yes thinking this is the Spring Break of Asia or something like that??
