Hi Zak
There is entry no barrier to our car park and the warning
notices
and (fake) clamping notices on the car park walls are ignored.

The fake notices are a good idea, but you need to reinforce them
with some
psycology.

Put up some new, bigger notices that look differenet. The
inference is that
a new company has taken over.

Beg borrow or steal a wheel clamp. I think you can hire them. Or
make a
mock one from MDF & paint it bright yellow.

Fix this to your own car with a big label on the windscreen in
yellow/black.
Leave in conspicuous position. Repeat next day with neighboors
car.

They'll probly get round that one by clampin their own 4 wheels of
the car.
