Tell us a story of culture shock you've experienced.
I don't know about shock, and there are many examples I could give, but I'll just mention the one. I was in the capital city of a third world country and every time I would go out I would be assailed by beggars, most of them children, scam artists and street vendors would call out to me, going so far as to following me around to bring me back to their stalls. Being white, they could safely assume I would be among the 5% richest of the population, and even better, a sucker.
