Looks like pure Barberism. The downside of the way the club is run (which is mostly great except for stuff like this),
Just sell a ticket and let someone in to watch a match FFS, and don't be an asshole if they can't come - let somebody else come and watch the team in their place! It's not difficult............and if it's somehow losing revenue, it's losing more than that in good will.
Years ago, when Barber first started calling us "customers" I warned that he would "squeeze fans until the pips squeak". I rest my case.
