The genie granted me a packet of Tim Tams that never runs out.
I supplemented my income by filling empty packs from my endless packet and onselling them. It became an industry in itself. My costs were low and I was able to undercut the manufacturer. Eventually the manufacturer stopped making Tim Tams: they couldn’t compete.
I’m the only supplier now. My days are spent transferring biscuit after biscuit. I have become a biscuit battery hen, thanks to the gift—curse—of the genie.
why would you not just sell the endless packet back to the manufacturer, in exchange for a mere lifetime's supply...?
