Personally I don't like being lectured at. I think he could have phrased it better.
I've only left a game early once (5-1 v Tranmere), never arrive late or leave early to get stuff to eat etc. and have only gone into the concourse area during play a couple of times ever due to an absolutely desperate need for a piss. But I'd be tempted to leave the next game early just as a 'fuck you' to Doug.
People have all sorts of reasons for leaving early. Including just because they fucking want to! They're paying their money, they can choose to stay or not. In fact, as a customer, blame the players and management for not putting in a decent enough performance and result that they don't want to stay. Sure, it's a bit fickle given the results of the last year, but people have got other shit to do than sit in the cold around Christmas getting annoyed and frustrated at a load of overpaid men not doing their job properly.
