I have noticed a dramatic change in tourist behavior in the last 4 years or so. I literary have been hit in the head by people welding selfie sticks too engrossed in getting pictures of themselves to pay attention to others in a crowded area. What's worse is the people who are repeatedly asked by staff to refrain from doing something and just blatantly disregard instructions. I never saw this happen before the age of smartphones and cheap DSLR cameras.
