I’m in Dublin, Ireland. It is not common, but not uncommon. Kids and teenagers zip around high-footfall areas in the city centre (such as our financial district) on escooters and electric bikes, and literally grab the phones out of your hand as you’re using them. Minimal violence because they know they’d likely lose, but still pretty traumatic and the Gardaí (our police force) are two swamped in everything else to do a thing about it.
I know four people it’s happened to in two years, all four of them women.
