As for the daily washing, makeup and such, it was all pretty casual.
At that time, the mindset was just that it would be good enough to stay alive.
If it wasn't for Sean Knight and Lincoln Harrington, at the mountain pass, when the convoy encountered those black men, they might have had to resort to paying them off, and there would be a great chance of being threatened.
Manager Thompson had a gun over there, but it was unclear whether it could be useful - although the company underwent some necessary military training after entering Africa.
But for non-military personnel, such training or, more appropriately, orientation, is more out of curiosity. How much of that training could be remembered when an actual crisis occurred? No one knows.
So, most likely, they would have ended up like those people behind the mountain, being robbed and then... killed.
However, Sean Knight and the others didn't seem to be alarmed at all by the situation. Instead, they actively confronted it.
