I don't see the big deal is every gambler knows that sex appeal is a marketing tool, most of us are so use to this we hardly notice the stuff. Would you tell waitress in a casino to go put some clothes on or tell the management that your shocked that they allow this to go on? NO, you wouldn't because you walked in the casino expecting and knowing this is how they work!
There are many different ways casinos will try to appeal to each gender, look at "Ladies Night Out" by micro that is geared towards woman, they even gear the games to fads such as "Loaded" we all know some people think gangsters are cool(get real people...lol), others could have viewed it as racial prejudice and taken all of micro banners down.
Anyway if anyone wins a trip to see Hugh take me with you!!
