Actually there was one kind of odd thing I remember. In some casinos in Germany (for example) you have to have a suit and tie - if you don't, you don't get admitted. However, you can borrow/rent one from the casino for a small fee.

Gentings had the same kind of thing, however it wasn't a suit/tie, it was basically a logn-sleeved hawaiian shirt (it was batik - but for those who can't picture it, hawaiian is close enough). Again, you could borrow/rent one on entrance.

I checked the site and it is still a requirement (along with a shirt/tie). Kinda fun as I remember.
