Rules are vague, yes that is the worst part. At least Saudi just declares their rules and sticks to it. Even if we don't agree with their rules, they are not being hypocritical about it.

Here, they don't want to lose their cultural values like Dubai, but they don't want the reputation that Saudi has either. They are trying for the best of both worlds here, so they don't publicize their rules and people are in for a rude shock when the rule gets suddenly sprung on them.
