What cultural faux pas should I try to avoid making in Lagos?

"In Lagos, it is important to be respectful of local customs and traditions. It is considered impolite to be overly loud or to talk about sensitive topics such as politics or religion. Additionally, it is important to dress modestly and to avoid public displays of affection. It is also important to be aware of the local laws and to respect the authority of police officers. Finally, it is important to be mindful of the local environment and to avoid littering or damaging the environment in any way," mentioned another expat when asked about moving to Lagos, Portugal.
