Clothing Modesty is key. Shoulders and knees covered at all times – for both sexes – is a good rule to stick to. Swimwear is only for the beach.
Greetings Soft handshakes are normal (and firm ones seen as disrespectful). Unless a woman offers her hand first, men should refrain from shaking hands with a woman.
Politics and religion Avoid contentious issues such as the UAE's involvement in Yemen and the Qatar blockade. Insulting Islam is against the law as is publicly expressing sympathy towards Qatar.
Public displays of affection A no-no. Couples should refrain from kissing, cuddling or hand-holding in public. Technically all are public-decency offences, though most people turn a blind eye to hand-holding.
Ramadan Drinking, eating, smoking, loud music and dancing in public during daylight fasting hours are illegal.
Swearing Considered highly offensive and people have been prosecuted or deported for it.
