Although, more recently, women have begun working as store clerks in department stores or at grocery checkout counters.
Regardless of the type of employment they pursue, women are always required to cover their faces during working hours.
Also, a lone man or a group of guys will not be allowed to enter a mall unless there is a woman with them.
Some restaurants are even divided into two sections, one for single individuals of either gender and the other for families.
Although most non-Muslim expats or westerners will be excluded from this cultural practice, you should still be aware of why and how these social situations work in Saudi Arabia.
All Muslims, under Islamic law, are not allowed to eat pork.
Females are not allowed to drive in Saudi Arabia; this is one of the most notorious bans related to women in Saudi Arabia.
This law attempts to prevent women from leaving their houses without the accompaniment of their spouse or male family member (see #1), and avoid the potential for them encountering unrelated males without their own male family members or from getting into situations where they would have to uncover their face.
Flower shops and gift shops are not allowed to sell roses or heart-shaped novelties either.
Stores that refuse to abide by this law can be closed down, and students seen wearing something with a hint of red on are usually sent home from school to change clothes.
