At least back when I checked this was the case...All you had to do was sign a waiver when you went in. They also, of course, wanted all payment up front.

I don't see what's so hard about that. If you ask me, it's moralizing, not legitimate concern. Waivers are for protection from liability.

I think people just like to beat their chests and moralize. Makes the little ones feel bigger...or something. ;)

Cheers!
