RESPECT!
Moroccan customs and beliefs are often surprising for the outsider. What you consider normal behavior might be considered rude to Moroccans, just because of your sheer ignorance.
For example, don’t take your top off at the beach, walk around in provocative clothing, or walk into a Mosque with your shoes on (you won’t be allowed in if you’re not Muslim anyway.)
Be respectful of local customs and you will reap the rewards of Moroccans’ legendary hospitality.
