Armenian society places importance on respect, family and tradition. Greetings are usually warm but polite; a handshake is common when meeting someone for the first time. Among friends and relatives, greetings may be more informal. It is customary to address people using titles and surnames in more formal settings.
Dress standards are generally relaxed in Yerevan, though modest attire is appropriate when visiting churches and monasteries. When entering places of worship, visitors should dress respectfully and avoid loud behaviour.
Photography inside churches is usually permitted, but flash photography may be discouraged and it is courteous to check before taking pictures during services.
Tipping is appreciated but not strictly obligatory. In restaurants, a service charge of around 10% is sometimes included in the bill; if not, leaving around 10% for good service is customary. In cafés, rounding up the bill is common. Taxi drivers do not usually expect tips, though rounding up the fare is considered polite.
Hospitality is highly valued, and guests may be offered food or drink when visiting a home. Accepting at least a small portion is considered courteous. Conversations can be animated and expressive, but public displays of affection are generally modest.
