Certain body language will sometimes offend people in Oman: Do not point directly at people. Don't show the soles of your feet or shoes directly so that people can see them. Public displays of affection between sexes e.g. kissing, hugging, and holding hands are most definitely frowned upon. It is considered polite not to smoke in public although there are no smoking signs posted where it is actually prohibited to smoke. Alcohol is not completely illegal, but it is only legal to drink in licensed establishments. Be careful when taking photographs of people, especially women, always ask permission. It is also a good idea not to take photos of any thing that could be even vaguely related to the military.
