The local circumstances should be the thing that determines the entrance price and the local promoters/organisers should know how to set these. We all know that London event prices are higher than outside of that city - but then salaries in London are generally much higher because of the cost of living in the metropolis.

Conversely, quite a few years ago I went to an event on the Fylde coast. Innocently, I mentioned the low admission prices to the organiser and was told firmly, "Do you know what the unemployment rate is in Fleetwood?" Well, no, I didn't - but the next morning I took a walk round the local market and by the look of the poor quality and low prices of the goods, I did get the impression that there was not a lot of money around.
