As an expat, and speaking primarily in English to the people I meet, I've had a lot of:

• "So where are you from?"
  "I'm from France"
• "Oh really wow, say something in French"
  .... uuuuhhh no, I'm not your monkey (that's not very nice for monkeys. sorry monkeys)
  I do have to admit that China can be a bit tough sometimes as a foreigner. The repeated "Hello's" and "Can I take a photo with you?" are intense - to say the least.
  I think the best attitude to have is to have fun with it. Find a few replies that make you giggle or have a friendly/quick question for them in their language. It will usually leave them pretty stunned as they probably did not expect it, no need to wait for their answer, just let them ponder and watch their perception of you slowly alter
