Have they got Fisher back in to write the press releases?
In all seriousness they need to have a huge clampdown on people taking the piss with kids tickets being used by adults. That was obviously the idea behind the initial pricing and pushing the kids to the family zone. Even if it means more staff check tickets before you get in the ground
Pre-covid they used to check your ticket before the turnstile, no reason this can't be done again. Colour code tickets / season ticket cards so it's very easy to tell who is using a concession ticket. As has been said several times easier to not let people in on the wrong ticket than try and kick them out
