I think you'll find the laws are pretty bloody strict the world over, just very difficult to enforce. I know for a fact a lot of people all over the place flout the rules, it should definitely not be promoted on a forum like this.
Last time I did it I had it drained by an aircon professional for free, ask nicely and be flexible with timing and I'm sure you can find somebody similar locally. Worst case you might have to bring him a cold beer (or warm, whatever you like)
