Indians it is easy. Just fly into LHR T3 and they wont even know they are out of Bombay, and even UK boarder-FBI-CIA will speak to them in their own language!
.....by the way that was meant in jest. I suppose these days I'd be in trouble for Un-PC writings on a forum by the ever-so-offended, but it was a J-O-K-E. I work with all nationalities, Norwegians, Indians, Swedes, Venezualen, Filipinos, Nigerian, pakistan and they are all a good bunch. The Nigerian guy hasn't even tried to scam me! - oops another un-PC joke (but he'd get it)..sorry....but anyway I have been called a Limey, a pom, wan*ker, etc and my feelings aren't hurt.
