Traffic warden, parking attendant, CEO

I'm amused to learn that parking attendants (formerly known as 'traffic wardens'*) now go by the official name of 'civil enforcement officers'. There are two reasons that this amuses me:

• The acronym for civil enforcement officer is CEO, which obviously is already used for 'chief executive officer'. Are parking attendants trying to sneak themselves some kudos?

• Parking attendants are, in my limited experience, sometimes less than civil. But then they are often given a less than civil reception by members of the public...

* Apparently the difference between a traffic warden (pictured) and a parking attendant is that the former is employed by the police whereas the latter is employed by a local authority. I did not know that!
