Is there a 'fair' rule of thumb for tipping in India? On one hand, I don't want to be a cheapstake and get my food spit in, but on the other hand, I don't want to support the worldwide American tradition of overtipping and making it worse for future tourists. I am going to India this December and I look every bit like a tourist, so there is no blending in with the locals. There aren't too many 6'0" white men running around India (I think).
