Then as others have suggested I will trip you and use you as a foot rest.

You are rude and unaware of the fact someone (prolly) has paid extra money to sit in that row and use that space. It is not yours.

Just because the bank is closed, does not give you the right to shoot out a window and get your money.

Perhaps more reasonably, if the route to your back yard from the front is obstructed, are you going to simply use the space beside your neighbours house then scale their fence/hedge without even so much as knocking at their door and explaining yourself?
