There's nothing to worry about as this is like Malaysia.Just don't take photo's without permission,ask an Arabic lady for directions,sit with the soles of your feet pointing at your host and don't use your left hand.Dealing with Arabs,you should always greet them first,as it's impolite to start a conversation or request without a greeting.Easy...!It's not Saudi and you should feel like you do back home in Malaysia.Good Luck!
