George has gone into a shop to complain about a very expensive firework he was sold which didn't go off. The shop assistant says that makes it a 'firenotwork'.
George is apoplectic. He spent upwards of fifteen pounds on an elaborate Catherine Wheel but it failed to work. Not only that, it was meant to be the piece-de-resistance of his fireworks display and made him look like a bit of a lemon. The were hushed voices afterwards.
This woman is not the manager of the shop. She is only working there for extra money as she tries to become an actor or a singer. If the manager of the shop, which sells novelty items and fireworks, heard her quip she would be fired on the spot. George's anger has turned into confusion as to how anyone could be so stupid.
In the end, George's money is not refunded because he threw the firework at the wall in anger rather than returning it with a receipt. It was his own fault, but he won't be buying his fireworks from there any more.
