I often wonder how people like that can actually enjoy their job, or feel a sense of fulfillment in doing a good job.

Surely when doing things like that, they have to be thinking "I'm a total ballbag for ticketing and harassing this guy for absolutely no sensible reason, and by doing so I'm allowing dangerous motorists to go out and kill people instead...My job is so worthwhile !" ?

How can anything else be going through their heads ? Apart from fresh air
