"Parcelforce mate, delivering your package. Sorry its a bit late"
"Sorry don't want it anymore. Can we return it under the Sales Of Goods Act as it isn't actually what we wanted."
"No"
"Oh I see, you can't take it back? Why's that then?"
"Because you the customer f****d around with the order so much that no one else would want it now anyway..." 
"Hmmmmmmm, OK. Perhaps if we chuck a few quid at it we could fix it and no one would notice, would they...?"
