The concept of convenience stores is not unique to North America. I have shown a modern convenience store selling all of the essentials required; gasoline (in the glass jugs), diesel fuel (also in the glass jugs), water (in the returnable 5 gallon containers, and all of the modern electronic equipment that you can imagine.
This picture was taken in Bushtown, outside Monrovia, Liberia. This is during the period after the civil war when there were none of the utitlities that we are accustomed to. There was no running water or electricity in the country. Fuel for cars was delivered in containers, or, if you were fortunate, by means of a gas pump modified with a hand crank.
