Are you indian / have you actually observed this? I'm Indian-American and in my experience this has been entirely non-existent so this article kinda baffles me. I've been asked whether I'm vegetarian before, but always in the context of grabbing food (respecting dietary preferences), and certainly haven't noticed any discrimination after saying that I'm not. I worked in SF for a year and currently in Seattle. Have several Indian friends/colleagues aswell and not once have I ever heard caste brought up
