Today was my lucky day - still got my camera - even if I looked silly with it around my neck drinking coffee!
While enjoying a cup of coffee taking photos, guy you can see in the left hand corner - also taking pics of his friend, put his camera down for a minute, was distracted by a guy who picked up a key on the ground and passed it to them, continued walking away and someone walked away with his camera in another direction - in seconds. Ironically, it was a Nikon D3000 he bought on the black market in India. They are that quick!
Keep that strap around your neck!
