I got forcibly ejected from Durham's ground because of a beer snake. They go over the top with them. Nearly got arrested for it as well. Admittedly the arrest part was because I refused to move away from the ground, sat on a curb for an hour and a half and told a police wifey to fuck off. But still.... I don't see the harm in them.
Got full sympathy with you. I bet you weren't causing any trouble yet the coppers were getting power mad insisting you moved away from the ground. Wankers.
