According to the Foreign and Commonwealth Office of the United Kingdom in its online guide for living in or visiting the United Arab Emirates, there are some basic social rules expatriates must keep in mind as to not offend cultural norms.
* Keep in mind that you are no longer in the UK. Respect the laws and values of the country and your stay should be an extremely enjoyable one.
* The UAE is built on generations of Islamic traditions that are rooted firmly in its culture and tribal heritage. These traditions have been passed down from generation to generation and form the cornerstones of everyday life for an Emirati family.
* Alcohol consumption is allowed only by non-Muslims in licensed restaurants, pubs, clubs, private venues and at home (for residents who have acquired an alcohol licence). For those living in the UAE, a special licence must be obtained before purchasing alcohol from licensed stores.
* Drugs are strictly forbidden. The penalties for drug trafficking, smuggling and possession of even residual amounts of drugs are severe.
* Sexual relationships outside of marriage are illegal, irrespective of any relationship you may have with your partner in the UK. Cohabiting, including in hotels, is also illegal.
* The UAE has a zero-tolerance policy towards drinking and driving. You can be charged and imprisoned if you are caught with even the smallest amount of alcohol in your system.
* Offensive language, spitting and aggressive behaviour (including hand gestures) are viewed very seriously and can result in imprisonment and deportation. This includes ‘road rage’.
* Holding hands for married couples is tolerated but kissing and hugging are considered offences against public decency. Open displays of affection are generally not tolerated.
* Smoking is forbidden in government areas, offices and shopping malls. There are, however, many designated areas where smoking is allowed. Working without the proper visa is illegal.
* Emiratis dress conservatively in traditional dress and can be offended when people dress inappropriately or not in accordance with Islamic values. In public places such as shopping malls, restaurants and parks, you are encouraged to dress appropriately.
* Islamic religious values are greatly respected in the UAE. Showing any disrespect towards religious beliefs or practises is considered deeply offensive and very likely to result in a heavy fine and/or imprisonment.
