Under John Coughlin we played 100+ games and only ever conceded the first goal but came from behind to win once. That was away a Albion Rovers. I left after 35 minutes, about 5 mins after they scored.
I've left away games before half time on a few occasions, sometimes I've been on the supporters bus and so gone for a walk or a pint, sometimes I've just driven home if I have the car. I know we play at a fairly low level but the games are often entertaining in their own way. When I'm simply not getting any enjoyment (have stayed til the end in 5,6,7- nil defeats) I just leave.
