I have no issue with people leaving before half time to get a drink or whatever. But don’t then expect to force your way back down the stairs to your seat just after the whistle has gone when 99% of people are going the opposite way down to the concourse. And that includes the dhead in WSL who had a rant because he couldn’t get back to his seat. It’s generally good to use a bit of common sense and wait until the flow of people has stopped.
