As Coco has said, it's more about routine.
Most people have a routine for match day. Whether it's having to get stuff done before the game or, having time to do things afterwards, it's all about routine.
The many small changes that have been made this season, where you can enter the ground, smoking, access to the various bars, drinks policy, where you can stand etc., etc. disrupt everyone's routine. and many of the changes appear to have happened for little or no reason and based on the fact that our support base like a moan, it all does nothing to improve the match day experience.
The club need to do all that they can to encourage supporters to turn up every week and make the home games as enjoyable as possible and although they have made massive strides in stabilising the club as a whole and ensuring that we have a club to support, some of the small changes have alienated fans, rather than encouraging them.
Our group always had a couple of pints before the match in the bar at the bottom of "the flats" but with the changes to access, we now meet in one of the pubs close to the ground and unfortunately the price of a few pints goes over the counter elsewhere.
This happened purely because we were unable to be sure if we could get into certain places within the ground.
We had done this for many, many seasons but this season it became a lottery.
As for KO time, it doesn't matter too much as long as the club sticks with it but, people do need to get used to it and for each person that it helps, it probably hinders someone else.
Perhaps if there had been better communication ie the kind of savings that Snowie mentioned, perhaps people would have better understood the reason for change.
