For 42 years I was in the merchant navy. Before the jobs dried up deep sea it meant being away from the UK for up to eight months a year, with leave in-between. When home on leave I got to every game I could. We weren't great back then so getting into games home and away was doable and I did so. When those jobs dried up I ended up working on cross channel ferries in Dover in 1987. This was a week on week off basis. I bought a season ticket then even though due to my shift patterns I missed a lot of games and it cost me more having one. This was the days before seat exchange etcetera. The club were happy to take my money whether I turned up or not. Obviously we were a different financial animal back then.
Anyway I've digressed slightly. The point is many people have jobs where their shift patterns will mean they can't personally attend games. They keep their season ticket because they want to be amongst friends and families when they can attend. Only a fool wouldn't put it on the seat exchange or pass it to family or a friend if they can't attend. What's the problem with that?? The club will often make more money by selling it for more than the season ticket holder paid for it. There is absolutely no reason whatsoever for this ten game ruling except to get rid of season ticket holders who could fall foul of it.
