A pair of pickpockets tried to snag my headset, hoping that the phone would follow it. They hit fast, so I wouldn't have time to react.
The final result: the phone stayed safely in the deepest reaches of my bag, but the headset snapped in two unusable, irrecuperable halves. They got away with one half. I threw the other half at them a pair of seconds later. "HEY! YOU FORGOT THAT!"
Hey, they ruined my headset, ruining their favorite spot by drawing attention to them was only fair.
