We're going round in circles.
As far as I'm aware, there is no club in the Premier League that don't offer kids and senior concessions (even if there are some restrictions/limits on them) and I don't expect City to be allowed to be the first.
That being the case, I expect City would be forced to at least offer something like Arsenal, where kids and seniors get a discount on the adult prices in part of the stadium. If that happens, then the whole principal of one price for all is finished and they might as well offer concessions anywhere.
Arsenal offer concessions in a small part of their ground and nowhere else. They haven't accepted your logic and I doubt Ehab will either. Policing concessions in three blocks is a lot cheaper than policing it in the whole ground.
