Well, the implied ethnicity of the poster is non-Indian, so in addition to the embarrassment of having to spell out obscene words, there's the cultural gap as well. The poster can't judge how offended the call center worker was, and probably feels like he's poorly representing his culture. I've had many similar experiences, especially since I've been living in Korea recently, and it's very uncomfortable not knowing exactly how big of a faux pas you committed.
Well he was, and that's part of the story. I wasn't passing judgement on him as a person, or stating that because of that one characteristic he was Evil.
Edit: see my response to shard. No offense intended, and I hope none was taken :)
