The son of an Indian billionaire held a wedding celebration near to my living quarters last weekend - the marquee itself must have cost upwards of £100,000 to hire - they are still dismantling it nearly a week on from the event. It was clearly a very exclusive event judging from the security in force on the night itself. But a very expensive fireworks display to round off the evening offered a classic example of a free-rider. For some the pyrotechnics were great fun, for others, unaware of the event and with animals disturbed by the size and scope of the display, there was little they could do to reject the effects and no way that appropriate compensation could be paid.
