I used to work in a call center with a woman who had a typical South Asian accent. She was born a US citizen, but she grew up in Indonesia, India and Thailand. Often, she'd get some blockhead on the line who didn't want to talk to her, who wanted an "American" rep instead. Had nothing to do with where she was or how she did her job. It was only because they perceived her as foreign - as if an American can only come in one or two flavors.
