As s Sikh Brit that also wears a turban I usually feel quite at home when I'm routinely in the US. Hardly any noise direct my way (must have got lucky) but plenty of folk do glance in a curious sort of way.
People seem to remember us more which is no great surprise given we tend to stand out a mile.
Back in my consulting days I used to work a lot at Microsoft offices around the world. For some strange reason no matter which country I was in, the local staff used to assume I was there for a speaking gig!
But I'll never forget the time I went to Argentina -- the whole airport stopped as I got off the plane. I didn't go back there in a hurry...
