I find the guy bothered by people stopping to take photos a charmer. Hope I don't run into him over there, but I'm never without a camera when I'm abroad. When I see a tourist taking a photo either in Calgary or nearby Rocky Mountains, I'm always intrigued by what their subject matter is and the angle of how they're capturing the image -- that sort of thing. Hardly a bother!!
I guess they don't realize how important we tourists are to the economy. According to Visit Britain website, tourism is the 5th largest industry and provides 3,000,000 jobs. Nothing to sneeze at.
