In Amman, male tourists should be mindful of their clothing choices and avoid wearing shorts, short-sleeved T-shirts, and tank tops. As for women, there are different rules of behavior, such as refraining from sitting in the front seat of a car and avoiding physical contact with men. It's also essential to exercise caution when taking photos, as photographing military facilities is prohibited. Despite these considerations, Amman is generally a welcoming and friendly city for tourists.
