Actually it might do em a favour tbh. A flask full for a sixty year old I'd guess at least four visits to loo.
Remember a few years ago my mate took his camera to a game and got permission from the club to take pictures- he had to pick a letter up from the box office. That must have been more than 10 years ago
I doubt it takes anything away from the club financially or indeed impacts the number of supporters in the ground. Quality of these streams are terrible, literally unwatchable, certainly can't see how anyone would get any sort of fulfilment from watching someones facebook stream. It's not as if people are setting up with the pro equipment up in the gantry, it's people using a mobile phone capturing blurred images (lack of optical zoom), add to that the crap sound quality and the people in the row in front standing up blocking the cameras view every 20 seconds because we have won a throw in (never understand that). I get that this may be against FL rules but, seriously they need to relax if it's a high priority concern about losing any customers. Anybody would think ITV had sent undercover agents in to secretly film highlights lol..
I went to a game the Nou Camp last year. If everyone who has a camera that day and used it during the match had been thrown it it probably would have been about 1/8th full.
