Even if that were true, whoever at the club in a commercial role responsible for employing these sub-contractors should be going down there and making sure things are done to acceptable standards, and it not , then the contract either isn't paid or forced to rectify it.
This process happens on building sites every single day of the year 1000s of times over. Its not complicated.
At stoke they have a big outside area behind the away end where people can go and smoke/drink etc... And the bars inside the concourse have a second counter facing outwards where people in the outside bit can get served from.. it's very simple but very effective, they've doubled their concessions capacity instantly and made the toilets 100% a smoke free zone in one simple move.
This has been put to the club loads of times through RAWA and the club have said they have absolutely no intention to do similar with an outside area as it's too costly and , apparently, when they asked other clubs like stoke about what set up they have, they were told that the other clubs wish they never did it as it's too costly and too much chew on..which is a total lie. It shows what the likes of David Bruce actually think about us fans. They wouldn't give us the steam off thier piss
