You see, you may be in a developed country. But in our country, Cameroon many petit business if not most are uneducated men and women who are in their 50's and 60's. How do you explain these things to them seeing that they too haven't ever gone to school? And the luminosity of the phone cam still highly affect them?

Well if you want another reason, as i stated, the big hands of the government can make the tables turn for their favour at every moment and embezzle funds.
