I understand what you're saying about it being against regulations and I can't argue against that fact. The main point for people sitting there, though, is that it is pretty much 100% of people in the area stand up and there are no problems amongst fans (i.e. getting in the way of other fans) as everyone seems to want to stand up.
Also, unless it was just a throwaway comment that you don't want to stand by, your comment about it only being poor/scummy people sitting there makes you ignorant and makes you come across as extremely unintelligent. The 'singing section', as mentioned by others, is on the whole people who used to sit in the main part of Leazes Level 7 who were moved due to the new away section. The club set the prices for this new section; are people going to request to pay more for sitting there?!?
