I see the sibling says "Indian" could be considered wrong.

However, again, with you post why is it wrong to say their ethnicity? Incidentally I was plugging for American as being an indicator of ethnicity; there's also a subset issue so for "sleazy American diner" read "sleazy Greek bar" (a bar in Greece, though it could be a bar run by a Greek I guess it doesn't seem to matter).
