Try not to judge others by your own standards.
I'll elaborate for you so that you can maybe better appreciate my situation before you try to stick your label on me.
I have a medical condition that lots of blokes get in their 50's. It's a prostate issue that causes you to need a piss as regular as clockwork - it also makes you piss slowly (you should read up on this stuff because it'll happen to you or to friends of yours soon enough). If I drank a gallon before going in the ground then I'd spend the first half stood at a urinal and not see the game.
As it is I was always desperate for a piss by halftime but also thirsty because, with this condition, you need to keep your fluids in check so that you can last until halftime.
In the halftime interval you only have time to have a piss (especially at the speed I do it), or queue to buy a drink, before the second half kicks off and there's no way that I'd attend a game and not watch it in it's entirety.
I used to go take a leak at halftime then, when the second half had started and the straglers had returned to their seats, I'd pour myself a coffee and get my fluids back up. It seemed perfectly reasonable to me. I did it because of medical need.
I've only been straight in what I've written and I can't quite understand why you feel fit to poke fun. I hope you'll maybe reconsider on reflection.
