I'm sure traffic wardens say the same thing
I actually spoke to one traffic warden who, after giving me a ticket, told me that "we work to provide a necessary and valuable service to the public."
Ironic, since I was on hospital business at the time, and parked in the hospital car park (which is run by a private car park firm, sadly).
A traffic warden?! I've never been so mortally offended in my entire life.
