Not sure how you’d even do this? I know I’m poking fun, so no offence meant here but can you just imagine the conversation?
“Ticket Office here, Sir. For the coming season, are you planning on singing? or enjoying the view from up high and not singing? If the latter, Sir, I’m afraid we’ll have to move you from the seat you’ve sat in for 10 years. We need to give it to some youth who wouldn’t sit in his allocated seat and helped contribute to parts of the ground being shut. But he’s a singer you see, Sir, and that’s what we need.”
Then I’d assume six months into the season to another ticket holder:
“Hello Sir, this is the Ticket Office. We’re calling about your seat and more specifically what you’ve been doing in it. We see you’ve attended all home games and spent money at half time and this is appreciated. However Sir, and it’s unfortunate there is a ‘But’, but you simply haven’t been singing enough. Yes, we’ve seen you clap occasionally, shout the occasional words of encouragement and cheer when we score but no contribution to “No Pig fans in Town” or even just the “Sheffield United, Sheffield United” one. You are important to us, Sir and we appreciate you’ve been a season ticket holder for 40 years but the young lad three rows further forward, whom we see as a potential singer, well just can’t muster the confidence up when he’s sat a few rows from his mates. Please see it from his side, Sir. We’ve got some excellent restricted view seats however, or we can move you the other side of the ground where we hope it doesn’t trigger your vertigo. Up the Blades, Sir!”
