If you live out in the countryside though, you probably couldn't tell the difference between an Egyptian and Nigerian yet alone between an Iranian and an Afgan or Indian and Shri lanken. A Londoner would find it hard to explain to the country folk how they can tell the difference visually, but they can. Some white Polish women are easy for me to identify even if they are the other side of the street as they have uniquely Polish look, although only about 1 in 10 are that distinctive. Often the shaved head of the polish men and their look on top makes the guess easier although the men usually have thicker accents and not so good english too.

You can't be be 100% on nationality and time spent in the country but you can have a very good idea if you have lived in the right places.

Does this skill extend to knowing how much tax they pay?
