I was born and brought-up in Saudi, and the stuff that goes on there would put any Country to shame. The only difference is that it's done behind doors.. except for 'poondi'. Roam around Tahliya Mall and u'd see similar groups of men walking behind women, offering them their numbers.
Go to the underground parties, sheesha cafes and u'd see couples dating, holding hands etc.
CE, the tinted windows are because of the climate.. summers in the Middle East are horrible!
