Possibly. Some drivers seem to attract more runners (and bother, in general) than others. I guess attitude and general demeanour have some bearing with at least some runners being opportunists who'll take advantage if they detect a nervous disposition or, perhaps, simply conclude that the driver is unlikely to give chase, break their legs, blow off their kneecaps or even smash up their motor and/or gaff.
Personally, I've had extremely few runners and, while back when I wore a younger man's clothes (Anthony Kelly's) I might have given chase and/or wound myself up about them, these days I wouldn't bat an eyelid. Pursuing them invariably costs you money and fucks up your entire shift. Rather than think of the value of the fare think of the time they were in the car i.e. it's 5/10/20/whatever minutes of your life. In any event I'm too old/disinterested to fall out with anyone over a taxi fare regardless of the circumstances.
