Swan water is the safe drinking water to look for approx 80 naira for a big bottle. The cheap "pure water" sold in plastic bags is cheaper but not as "pure" as SWAN. EVA water, a brand by Coca Cola Company, is also safe.
Note that Swan water is almost out of ciruclation. It was popular back then in the nineties but has lost its market control now. It is better to go for Eva water by Coca Cola company or Nestle water by Nestle Nigeria. It is also of extreme importance not to buy water outside good-looking shops.
It is advisable to purchase bottled water from convenience stores rather than by the roadside. These upscale convenience stores usually purchase their supplies directly from the suppliers, along with soft drinks such as Coca Cola and other bottled beverage products.

If you are speaking the language, some of the languages have different ways for someone to address someone older than themselves. You do not hand things over to people, especially adults and people older than you, with your left hand. It's considered an insult.
You don't cross or jump over someone's legs if they are sitting with the legs extended out. It's considered bad luck.
Avoid shaking hands with elders and older people in non Igbo villages. It's disrespectful to do that. Can you bow down a little? Kneeling or genuflecting for women or prostrating by men especially among the Yoruba is the normal thing to do. You may not need to do it either, but just show some form of respect when greeting older people. You can get away with not doing that in big cities or urban areas, they are less traditional there.
If you want to go out with anyone friend, interest whatever the sex, it is customary to allow the friend if he/she is still living under their parent's or guardian's roof, to ask the parents/guardians first.

When entering a house in the predominantly Muslim North, you have to let them know in advance that you are visiting so that the women can prepare cover themselves up.

They will ask you to wait while the women are informed. Do not be offended by the wait.
When entering a house in the metropolitan area, you as a foreigner or visitor should endeavour to find the owners of the house and greet them and let them know of your presence. Do this when you are leaving as well. It is customary for your hosts to entertain you with food and drinks.
Airports can be stressful, as the organisation is a bit confusing particularly at Port Harcourt Airport. If you are White, be prepared to keep hold of a couple of "dash" Envelopes with a couple of Niara or American dollars, Nothing big, just a small courtesy tip, as sometimes Airport security take longer searching your bags on purpose, as they know and or assume you are wealthy, hoping for a small dash in order to make your search easier.
This may not always be the case, but if a general states "Do you have a coffee or mineral to give me", this is a hint that they would appreciate some dash.
