Thank you, @benthomaswwd the moderator, It was the same method of gas supplies and usages as your own method in the UK, when my family lived in Hong Kong many yes ago.

This is the best method of supplies, but in this side of the world, Nigeria, it's entirely a different method.

Everyone is on their own, we keep carrying our cooking gas cylinders around, looking for and going to buy from gas depots whenever it happened as it happened to me.

So painful and embarrassing, but what can we do? That's how my country, Nigeria is built up, many important things are just complicated.
Thank you for your time, I appreciate!!
