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 the US, much of the religious behavior during Ramadan is for show. Like Baptists not drinking if another Baptist is around. They will eat if no one else is around.
