How could people from other countries know this is not how you pay hospital bills in Nigeria?

Its kind of difficult to know how a medical bill is done if youre not Nigerian. Even, some Nigerian don't know how a medical bill looks like probably because they don't pay much kind to it.

I know there is no health care there, or maybe better said, not for everyone..... but those scames can more from every other countries with no health insurance.

Actually, Nigeria is more developed than most people think. There is health care for everyone in Nigeria given that they can get themselves to the hospital. We have hospitals, and PHC centers in many corners of the country. Though it may not seem enough, I think its sufficient.

We also have an insurance agency for health, National Health Insurance Scheme.
