Yeah thats why I added "to and extent" ie standing in the aisles/blocking views. I dont buy "killing the atmosphere" though as the like "offenders" may not be contributing too much anyway and it's not really selfish is it? (unless you are blocking someones view or something of course)
Each to their own again innit? If a pint and a pie is part of your enjoyable match day so be it. There is just way too much judgement and opinions (my opinion) on what is ok and what isnt for what other fans want to do, do what you like and what suits you (to an extent)
