The guy who answered was clearly Indian (subcontinent, not reservation). He told me his name was Jim. He had a very thick accent and I was instantly pissed off. Not because he was answering from India, but because he claimed his name was Jim. Had he told me to call him Ganesh, or Raj or Anoop, or even Dhruv, I would have been fine.
By my own highly unscientific estimate, about a third of our 20,000 or so local residents with Pacific Rim ancestry — we don’t really have a lot of Indian-type Indians — have sort-of-English-sounding first names, and nobody thinks anything about it. Then again, they’re here and not a couple of continents over.
