My preference is to draw two separate outlines.  One for parking, one
for the building.  Tag the building as
building = yes
shop = greengrocer
name = Coop

tag the parking area as
amenity = parking

For "extra marks" :-) I would add a driveway from the road to the
parking polygon and tag it:

highway = service
service = driveway

And I would be sure to connect the driveway at the road and the
parking polygon with a connecting node.

Let's look at the Melville Theatre, shall we?

I see a couple of problems here.
The garage is folded over on itself
There are stray nodes
The building appears too big
No parking is shown

I would map it as follows. You can do better, since you are there.  I
did not save my edits.  This is just an example.

Reduced the building size and added parking.  Does the building extend
further south?
Add driveway
Delete stray nodes
Detach building / garage

Enjoy.
