In the opening case on the Java Lounge in Saudi Arabia, people in the port city of Jeddah were less culturally conservative than people in the interior of the country. The most likely reason for this is that

the coastal area is secular$,$ whereas the interior of Saudi Arabia has a state religion

the coastal area has a culture with a higher uncertainty avoidance

the coastal area has to trade with countries using different religious holidays

people in the port cities have more contact with foreigners
