Im confused that you’ve said multiple times that the club had contractual reasons they couldn’t let you sell the book inside the stadium, although despite this the person at City dealing with you went to his superiors to try and find a way around their contractual limitations to accommodate the request (albeit unsuccessful), but still think you’ve been hard done by the club?
From what you’ve told us, Tommy and yourself decided the hospitality and hotel rooms from the club, plus being guest of honour at the Arsenal game and supporters branch, getting showered with adoration from old fans, reliving glory years and promoting the book wasn’t worth the £150(?) in petrol and the bother of driving down because you’d miss out on book sales which would net you £100 each?
Which is fine - no one would say you or Tommy are obliged to come to the ground when invited - but it’s hardly the story of new heartless corporate Manchester City forgetting its old heroes and treating them like muck on their shoe. If anything it seems a story of a bloke not being too bothered about his old club hosting and honouring him unless he turned a profit on the trip and cancelling a speaking engagement last minute when he did the maths.
Honestly my main takeaway from the story is that you seem to have taken it as a personal affront that the club didn’t break its contracts with retail partners in the stadium to facilitate you and can’t understand a 54,000 capacity stadium is run differently to Gresty Road.
Despite all that I will now go and buy a copy, and I wish you success with the book and your upcoming trip to Blackpool. Have you considered asking if the club shop or even the website will stock the book?
