I was in Saudi Arabia during Ramadan. They put curtains up in the mess hall so Muslims would not get upset or tempted to eat while us evil infidels ate. Many Muslims slept all day then partied all night. No alcohol, just a lot of food and socializing. The Muslims then went home before dawn and slept all day, it was pretty rough,hahaha
in prison they do the same, not much devout practicing and the wanna be musis come out to party.
