It is not to say that certain persons on weekends don't request the weekend rate at Kasane airport for visiting aircraft.
I recall years ago when a whole bunch of books for issuing speeding fines or receipts went missing, I got pulled over and the fine was to be paid in cash. I insisted on being given the ticket and paying it on my return to Gab's.
Seems it was my lucky day, the pen did not hit the paper and was told to go on my way.
They then asked for some cigarettes.
