Damen Tag (Womens day)

The Montesino casino in Austria had a promotion on which is probably not strictly speaking legal, but every time they have Damen Tag, any women that turn up don,t pay any entry fee into the tournament.
The promotion seems to work really well as I would estimate that of the 233 entries, probably about a 1/3rd were female, which is about 3 times more than you would normally get.
