That was my least favorite thing about traveling/living overseas as a stereotypical looking American. I hate haggling. I hate it more than anything. It's needlessly antagonistic and completely unnecessary. I understand it's a cultural thing, but I hate it more than birds.

It was exhausting to buy anything, the entire time. It never got better, even when the shops learned who I was after an extended period of time. Food, water, everything was an argument. I just wanted to exist and check out what was going on around me, not argue with some random shop that my groceries shouldn't be so expensive.

When I have traveled to India, I just wear jeans and t-shirt... and yeah, a backpack. :) Obviously, I am a non-native, but I have not experienced outrageous "foreigners-only" prices ever. This experience includes incredibly remote villages in South India as well as urban centre of Mumbai. That said, I understand that many people have difficult experiences with bartering when they travel in South Asia.
