Greetings
Greet people properly before getting to business: a handshake and a few pleasantries go a long way, in French, English or Pidgin as appropriate.
Chiefdoms and palaces
In the Grassfields fondoms and the Bamoun kingdom, the palace is a living institution. Follow the guide's instructions, dress modestly, and ask before photographing people or ceremonies.
Photography
Always ask before photographing people. Do not photograph military, police or government installations.
Religious sites
Dress modestly at mosques and churches; remove shoes where asked. Friday midday is prayer time in Muslim areas.
