When I was in China, I "fell" for the art expo scam. The guy and girl were nice enough, though, and although the prints were fairly generic, I still bought a few as a memento. I did bargain it down to something reasonable, and I actually knew about the scam, but still wanted to experience it for myself.

Got taken for a few tea ceremonies but never actually consumed because I began to ask to see a menu/price list.

I really don't agree with the disputing CC charges and contacting the authorities. If you walked into a restaurant/Starbucks/etc. and started eating and drinking before seeing the prices, you'd be fully expected to pay for it, regardless of whether you thought to ask how much things were or look at the price list.

Call it a lesson learned in foreign travel. And it's not like foreign tourists to NYC, LA, DC, etc. aren't similarly scammed.
