Personally I watch the players walk out onto the pitch (my favourite part of every match 🤩🤩🤩), then when the ref blows his whistle to start the match I immediately walk out of my seat, down the steps and back into the concourse so I can spend the next 45 minutes buying overpriced Chang beer at the kiosks. Then I go back to my seat to watch the players walk out for the second half (my second favourite part of every match 🤩🤩🤩). When the second half kicks off, that's my cue to leave the ground nice and early so I can beat the traffic
