If it was me, I'd probably want to head to the Pollok v Arthurlie game round the corner from the Shed first. It kicks off at 14:00, and will be done by quarter to four.
If anyone's thinking about this, the ground is ten minute's walk from Shawlands Cross (the Shed etc.) Entry is £6 full price, £3 concessions.
Match, pie and programme and change out a tenner!
And any number of decent boozers along the way
