I think you sound complete mismatched.
I think it's kind that he gives them away to kids.
In theory, I see your point. However, in practice, as I am very aware of the value of these tickets and the prizes you can get, I think you were being unreasonable.
You spent £40 for the fun of playing the machines and winning the tickets. Not collecting prizes, because the prizes are SHIT. Like 30,000 tickets for a lollipop etc.
You enjoyed playing the games and winning the tickets, I can't understand why you wouldn't do the kind thing and give the tickets to a kid, and then if you actually wanted some of the tat prizes, just buy from a pound shop or whatever.
Yes, it was your money and they are your tickets, so is it a red flag that he was being controlling? Possibly. It's hard to tell without knowing anything about him. But I know I would find it a massive turn off if somebody was doing this and I would suggest they gave them to a kid as well....as for the two of you getting in a fight about.....I think you just fundamentally sound very different.
