My mistake if he has 2 car spaces he should have 2 clickers.
I agree with Scotlandx I misread the origional post.
BUT RJSmith also says that
the owner of each car space is issued with a clicker for that car park to let them in/out of the building.
So if he has 2 car spaces the OC agree he should have 2 clickers. How do others who have 2 car spaces (and most likely 2 cars) get their 2nd car in / out.
