Yes I can imagine its not too much fun being in the front line on a Friday night!
As usual, its the minority of idiots spoiling things for everyone else. I was brought up in Winchester, which is an affluent town. But with 60 pubs in the small town centre, an army garrison, and plenty of farm boys coming in from outlying villages, there were literally pitched battles outside the Guildhall often on a weekend night.
Since I have moved to rough and ready Huddersfield which is much more working class, I am yet to see a pub fight in the 5 years I have lived here. Although someone was shot in a pub half a mile away on Sunday night so its not all good.
