Is there a new law in town regarding how to buy fuel?

In my area recently, I noticed the filling stations here have stopped selling fuel in kegs.

Trust Nigerians to adjust and improvise accordingly by detaching the fuel tanks of their generator sets and using it as substitution for Kegs.

I reasoned this was going to happen several years back and thought it to be ridiculous. Now I know better.

Kindly confirm if it's the same in your location.
