Algerian society is generally conservative and strongly influenced by Islamic traditions. Courtesy and respect are highly valued, and visitors are expected to behave modestly in public. Greetings are important; handshakes are common between men, while physical contact between men and women may be more reserved. It is polite to wait and see whether a woman offers her hand first.
Dress should be modest, particularly outside major cities and tourist settings. Both men and women are advised to avoid overly revealing clothing, and conservative attire is especially important when visiting mosques or religious sites.
Tipping is not obligatory but is appreciated for good service. In restaurants, leaving a small amount or rounding up the bill is customary if service has been satisfactory. In cafés, small change is sufficient. Taxi drivers may also be tipped by rounding up the fare. Hotel staff may expect modest tips for assistance with luggage or room service.
Photography should be approached with caution. It is generally acceptable to photograph landscapes and public spaces, but always ask permission before photographing people. Photography of military installations, government buildings, police or security personnel is strictly prohibited and can result in serious consequences. Visitors should be particularly discreet when taking photographs near official buildings.
Public displays of affection are uncommon and may attract unwanted attention, particularly outside larger cities. During the holy month of Ramadan, eating, drinking or smoking in public during daylight hours should be avoided as a sign of respect.
