Walk into almost any Starbucks in Saudi Arabia, and you’ll find signs guiding you to queue up based on your gender and marital status.

Most restaurants in Saudi Arabia have “gender walls” that separate women and families from single male customers. These walls are merely the cost of doing business in the country.
