Things you shouldn't do in Dubai
Be drunk in public. Alcohol consumption is illegal for the Muslim-majority population of Dubai, just as it is for many other parts of the region, such as Egypt. Non-Muslims are able to purchase alcohol in licensed bars, restaurants, and hotels, as is the case in many other Muslim countries, such as Egypt. But be careful not to have too many, as it is illegal to act disorderly in public, whether you are Muslim or not.
Take photos of people without their explicit permission. It is considered rude to snap a photo of anyone without asking them first – this particularly applies to taking photos of local women.
Swear. Cussing and foul language are considered an offense and a number of foreigners have got themselves in trouble by making vulgar comments in the presence of an undercover police office. Keep it clean folks.
Insult Islam. This is probably the worst thing you can do in an Islamic country. Regardless of your personal opinion on Islam, do not say anything out loud that might be deemed as disrespectful. Blasphemy carries serious punishments so if you have any strong opinions on Islam, keep them to yourself.
Flaunt your homosexuality. It is sad to have to say, but unfortunately homosexuality is still illegal in the UAE. Any public displays of affection between members of the same (or opposite unless married) sex could land you in big trouble. Cross-dressing is also illegal.
Use your left hand. This might seem like an odd rule but in Muslim culture the left hand is used for body hygiene and is therefore considered unclean. You should never shake hands or greet anyone with your left hand and you definitely shouldn’t be caught eating with it.
