People leave early because modern life is a bit shit. It happens at every ground in the country and is becoming more and more prevalent. Traffic is ****ing horrendous because every single road in Britain seems to have roadworks on it, people have too much work to do so need to get home to work.over their weekends so they can catch up for the work they are paid to do Monday to Friday, there are more drunken wankers about after games these days so people want to avoid them and, as ever, some people are just dicks.
It's not some ludicrous, tinfoil hat bollocks type protest at the football we are playing. I wouldn't do it, most people who sit around me don't do it but many elsewhere have done for years and will continue to do so, whatever the score.
