They’re on bikes, scooters, skates. Often they’re just on foot. Sometimes you can spot them in advance and get out of the way or hide. But sometimes they’re so quick, by the time you’ve noticed, they’ve got you and gone. They’re usually alone. That seems to be part of it. Some competitive thing, I believe. Some speak to you, shouting “thanks!” as they head off, looking for their next target. Some ignore you completely. You’re just a mark to them. They’re the worst. They make you feel like you’re just a thing: something to collect, a brand logo to scan.
