I honestly don't know if they will y'know...
on average, there will be around 15,000 more fans milling around the area on any given matchday... they gott drink somewhere!
The 'newbies' plastics and 'selfie-stick' brigade that we will inevitably attract, will no doubt immerse themselves in the 'new vision' of a matchday experience by buying up every last bit of merch, only drinking their watered down, over-priced fizzy pop inside the ground, and eating where they're told do by the club; "VIZIN ZE PERMIITERZ OF ZE GROUND, JA!"
...but for the rest of us (the other 30,000+ who have been going regularly for years) I honestly don't see what will change... other than the journey time home, to accommodate all the extra fans.
Pre-match, I'd imagine.hope it's as you were... the local Pubs will be fucking heaving!!!!
