Sounds to me like the guitar is capoed at the 3rd fret and playing in C.

Standing by a parking meter

In a cap she looked much older
And the bag across her shoulder

Had a laugh and over dinner
Told her I would really like to see her again

Took her home and nearly made it
Sitting on a sofa with a sister or two
Oh! lovely Rita, meter maid
Where would I be without you?
Give us a wink and make me think of you
