I imagine some bright economics-trained marketeer at Vue decided the ticket could be used as a bulk filler where seats could not be sold anyway. The marginal cost to serve an additional customer at the cinema is essentially zero, and a seat which would otherwise be empty earns no revenue anyway.
The problem with undergraduate economics is that it misses the human factor. The implicit licence to renege makes the cinema look like a cheat. Clare said that she doesn’t much like cheats and that her chances of going to the Vue again are slim.
So there you are - they might have been better just to stick with saying sorry (or giving us a genuine ticket).
