Buy a bic biro
Back in the 90's when i had a door to door delivery job it was always......
'what's that?' How the fuck do I know its a box with your name on it
'is it a bomb?' especially when I was round edgware/stanmore
'thanks for coming all this way just for me' wake up you idiot I've got another 90 odd deliveries still in the van
'why do i have to sign for it? can't you just leave it on the door step?' no I can't leave it on the doorstep dummy it will get stolen and probably your house will get burgled too
'why don't I get my post anymore?' what the fuck am I? a mind reader
