does this make sense to anyone else?

Apparently Scottish rugby officials have decided to stop selling game tickets on the day of the game. Only buying in advance will get you in the gate. The closest thing to an explanation this article puts forth is the claim it costs too much to pay the workers to be in place to sell same-day tickets. Also this:

"While there was some public criticism, most commentators accepted the SRU's rationale that experience had shown that far fewer people turn up without tickets than the organisation must allow for when making them available that way."

Huh? Why do you have to allow for a certain number of tickets to be available on the day of the game? You simply sell tickets for the seats which haven't already been ticketed. Bad luck if it's sold out ahead of time.

I can't figure this one out.
