Social interaction in India places strong emphasis on respect, politeness and awareness of hierarchy. Greetings are often accompanied by a handshake in professional settings, though many people prefer the traditional "namaste", made by placing the palms together with a slight bow. Public displays of affection are generally frowned upon, particularly outside major cities. Modest dress is appreciated, especially in rural areas and at religious sites, where shoulders and knees should be covered and shoes removed before entering temples, mosques and gurdwaras.
Tipping is common but not always obligatory. In restaurants, a service charge is sometimes included in the bill; if not, leaving around 10% for good service is customary in mid-range and higher-end establishments. Small tips are also appreciated by hotel staff, drivers and guides, while tipping in everyday situations such as taxis is discretionary.
Photography is usually permitted in public places, but visitors should always ask before photographing people, particularly in rural areas. Photography is often restricted or prohibited inside temples, shrines and government buildings, and signs should be observed. Sensitivity is advised when photographing religious ceremonies, cremation grounds or military sites.
