Oh come on you have been watching football long enough to know how long half time is just set your watch or phone to tell you when fifteen minutes is up. Hardly rocket science.
You say its dull (worse than Allbbiioonnn ??) but its the only time the massive crowd in the west get the opportunity to deliver their wall of noice, and it sound brilliant - its just a shame that is all you get
I never venture out at half time, I have a pie before the game, but a load of people round me came back saying there were no pies and no hot dogs. Surely by now they should have an idea of quantities that are needed.
