Tipping isn't strictly customary or mandatory, but rounding up or leaving a small amount is appreciated, and restaurants and bars heavily frequented by tourists may expect a tip of around 10 percent of the bill, while smaller establishments will not ; tipping local guides is always encouraged .

• Greet people warmly and take time for small talk before business — a handshake, eye contact, and a few words of French go a long way, as good etiquette starts with proper greetings: people value a friendly handshake, eye contact, and a few words of French before any request, question, or transaction .
• Dress modestly, especially outside big cities: wear simple clothes such as a t-shirt with pants or a skirt , and dress modestly when visiting religious sites.
• Always ask permission before photographing people, and never photograph military or government sites — taking photographs of military sites and government buildings is forbidden .
• Accept hospitality graciously: it is customary for hosts to offer food and refreshments to guests upon arrival, and refusing such offerings may be seen as impolite .
• Avoid public displays of alcohol consumption and don't flaunt valuables, as the culture advises against drinking alcohol just anywhere in public , and it's wise not to show off jewellery or watches.
• If invited to observe cultural or spiritual events like Bwiti ceremonies, be respectful — these traditions carry deep meaning, and Bwiti drums and songs from elders are not entertainment but memory, genealogy and the language of the forest people .
