our house is naturally a non-smoking home..

a few weeks ago a delivery driver knockeed on the front door with a parcel

he had a fag hanging out of his mouth..

in the minute or 2 it took to inspect and sign for the delivry,
even though he was standing outside on the front doorstep,
he exhaled enough of his noxious crap-cloud
to stink out our hallway and landing for at least a few hours later..
