There is literally no logical reason for the % of people that leave in the last 10 minutes of games. I get there may be a small % that might miss their last train or have some urgent matters to attend to but for the majority it is nothing more than habit or feeling that they need to beat others to be first in line for a bus or train, or just the fact that they can do what they want because its a free world.
People moan like hell on hear about the price of tickets, associated transport costs and the general cost of living to average fans, surely the best way to get the most value from that spend is to maximise the minutes watched for the money. Rocking up late, missing 5 mins either side of half time and then leaving 10 minutes early makes the £ per minute watched hugely more expensive.
All this is even without the fact that we have been given everything we could have ever wished for as fans by the club, we should be absolutely joyous and make the most of every minute while it lasts not chipping off early to get the best seat on the bus, or first row of the bar, or even getting to bed 20 mins earlier for work. Plus it also gives a psychological boost to the players and coaching staff.
One day in the future it might all be over, make the most of it while you can.
