I was in an organised session at Whitby and when the collecting tin came round NOBODY including myself put anything in the tin.There where people there who I know do not buy tickets, taking from the festival and not giving. Whitby is unique in so much as they do not do wrist bands but a lot of people do put there ticket on a lanyard. There are fringe type weekends, but at large festivals with a fringe, there are a lot of non financial contributors.
The festival obviously accepts this loss for the greater good of the festival.
