Wheel clamped, parking fine upset man about town (3)

I believe the answer is:
fop
'man about town' is the definition.
The answer and definition can be both people as well as being singular nouns.
Maybe there's a link between them I don't understand?
'wheel clamped parking fine upset' is the wordplay.
I cannot quite see how this works, but
'wheel' could be 'o' (O looks like a wheel) and 'o' is present in the answer.
'parking' could be 'p' (abbreviation on road signs) and 'p' is found in the answer.
'fine' could be 'f' (abbreviation in pencil classifications) and 'f' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for fop that I've seen before include "fashionable type" , "Gallant" , "Man excessively concerned with his appearance" , "exquisite" , "A dandy like Beau Brummel" .)
