Dubai seems like a place where things are bigger, brighter, and more modern in every aspect. The first sights that hit the eyes are probably the towering buildings, high-end shopping and very exotic things that grab attention right away. At the same time, the city is greatly influenced by the heritage and culture of the locals, which can be quite surprising for American tourists. It is not so much about hard and fast rules as it is about grasping the idea of what is usually expected in the open areas. Being aware of some of these limits beforehand will certainly make any vacation easier, more pleasant, and a lot more fun.
Public behavior and loud arguments

Getting angry or having loud quarrels in public places is probably not very appreciated. A quiet and polite attitude is the thing that will be welcomed most, especially in places that are always full of people, like shopping centers, public transport, and eateries.
Taking photos without permission

Photography of people without asking them is quite often the cause of awkward moments, if not worse. Particular attention being paid to the families, as well as private and government-related places, where it is not allowed to take pictures, is very important.
Disrespecting local traditions

A lot of the time, it really does come down to cultural respect. Things that would be almost normal in one place could be very differently interpreted here, and hence, being conscious of local customs and making small changes might prove very effective.
Displaying aggressive gestures

There is a possibility that the gestures that are considered very normal in the U.S. might be quite offensive here. In fact, I have found it a good idea to keep to very simple hand movements so as not to give the wrong impression.
Eating or drinking in restricted public areas

In fact, there are a few places or times when it is not appropriate to eat in public. What is more, one will often find out the ‘dos’ and ‘don’ts’ by watching the behavior of others.
Littering in public spaces

Being responsible for the cleanliness of the city is something that is probably being done seriously. Not many people would tolerate littering, so the best way to avoid any problems is obviously to use the bins that are meant for the purpose.
Disruptive behavior on public transport

Generally, public transportation is operating regularly, and any causes of distraction or loud noises will be immediately noticed. Most people are used to tolerating very little noise, and also they expect their personal space to be respected.
Disrespecting religious spaces

Generally, mosques or other religious places have certain rules that are expected to be followed. Remain silent and wear proper clothes to the place; this will definitely be a good sign of respect and will be appreciated.
Bringing certain items without checking rules

Some common things brought from the U.S. have different rules here. Knowing what is allowed before going to the airport or public places can save a lot of trouble
