The Brick Part

This is one to get you all thinking and yes its a two parter:
A builder is taking a delivery of 100 bricks to a site somewhere in Liverpool, when he gets there they say that the only wanted 99, but the invoice clearly states that they wanted 100.
After a lot of arguing and fighting the driver calls up his boss and tells him the situation that he's in.
His boss hangs up and calls him back and tells him to just give them the 99 bricks and take the other brick with him.
Off the driver goes and pulls up alongside Edge Hill station and after thinking about it throws the brick out the window onto the railway.
What Happened to the Brick? ? ?
p.s if you already know this twister then please don't answer ! ! ! ! !
