What are you doing here?

We are walking through Kigali on the way to the bus station when a white guy approaches us and asks "What are you doing here?". Well, traveling. "Yes, but what is the purpose of your visit?". Mmmh, holidays. "No other reason like business, just for holidays you come here?" The guy, which turns out to be from Kiev, doesn't feel comfortable at all here and apparentely wouldn't come here on his own. He was sent here for business and it's his first day in town. The next question is even better. "How do you handle security here? Do you carry a weapon?". Mmmh, probably not... (To put this into perspective. Kigali is a small city on cool 1500m above sea level and one of the most relaxed capitals in Africa. Guess it was his first visit to Africa.).
