Though there are a handful of gas stations in big cities, the vast majority of people buy their gas from roadside stands like the ones in the photos above and below. Gas is stored in big glass jugs, in 1.5 liter plastic bottles, in wine bottles and whatever other bottles are handy. Pull up and select the size of bottle you want. The stand will put a funnel lined with a rag (to filter out whatever was previously in the bottle) into your tank and fill ‘er up. The roadside gas is cheaper than commercial gas stations. It is illegally brought in from neighboring Nigeria whose oil reserves and subsidized gasoline keep the price low.
