I just remembered a funny scene at the old Sheraton Western Cape in South Africa. It's like Holland when it comes to saunas so everyone is nude. I went down to the spa early one afternoon and it was pretty empty. I was in the jacuzzi and an American couple arrived, I think on their honeymoon. Only they missed the sign at the entrance that is clothing optional. They got into the jacuzzi with me in their swimwear and we had a brief chat. Then as I stood up to exit the jacuzzi their eyes shot open and the woman almost screamed. She then looked around and saw another nude couple and you could see the shock and confusion on her face. I kindly let them know that America is not the norm when it comes to spas and that they didn't accidently enter a sex club.
