During my oil industry career I spent a lot of time in African countries. Senegal, on the west coast bordering the Sahara desert, was one of those places.
Part of my job was to oversee our onshore navigation stations. These were used for exact positioning of offshore seismic vessels. When I worked in Dakar (a city of 2 million) my driver would have to take me to those remote stations. Typically that would require a drive of 50-150 miles. The countryside was fascinating to see. We'd drive past small villages and towns. Places usually without petrol stations (gasoline stations to you Americans).
That meant that we would leave Dakar with a full tank of petrol. We'd also have bottled water and something to eat to take along.
We never took for granted that we would be able to purchase those commodities along the way. Water and food might be available somewhere. And it might not.
Not once did we run out of petrol or water to drink. If we had, I certainly would not have expected the government to pull up alongside and deliver those things to us. We were on our own and responsible for ourselves.
I'm just sayin' ...
