I cannot comment on Leamington particularly, but from some of the CCFC fans I know in Kenilworth, this behaviour is exactly what I would expect. I had numerous conversations with many of them who were trying to tell me why Wasps were a good thing over the years. They also used to get away tickets in some of the harder to get matches in too. Just generally behaved very entitled which was sad to see when some other genuine full time fans would miss out at their expense.
You can see one or two like-minded people on this thread seemingly thinking that there is nothing wrong with what is going on.
Mind you, if I can recall, that group of lads were normally the first to run a mile at the sight of 15 year old hooligans from ´little Scunthorpe´ throwing cans of Pringles!
