Unless your petrol station is on one of your regular routes, it's false economy not to fill up completely when you have an empty tank, otherwise you are incurring an extra trip to the petrol station. Of course if you can't afford a full tank, and are living hand to mouth each month/week, then you are in the poverty trap where everything is a percentage more expensive for you overall.

But the efficiency is lower driving around with a full tank.

  I think not. With a full tank there is less room for fumes to expand. I believe less fuel in the tank means worse fuel economy. Found this[1] from a quick search.

  In addition to my sibling comment, I'd point out that the weight of fuel is negligible in this application, especially in a smaller car. A full 14 gallon tank weighs half of an adult male. You'd save more fuel in the long run by losing some weight, but it still wouldn't be that much.

It’s expensive being poor. They also pay more fees for financial products and the like. For example poor people use expensive Western Union and rich people use wire transfer

Found this: https://theconversation.com/can-you-save-money-at-the-bowser-by-only-half-filling-the-fuel-tank-36260 https://theconversation.com/can-you-save-money-at-the-bowser... Very nice calculation. The results were that by filling up two half tanks as opposed to fully topping off one can get an extra 3.5 kms, albeit with a time penalty for going twice to the gas station. Hardly worh it as just making the round trip to the gas station would probably eat up those kms. To this I would add the wear and tear on the car by having it run longer with a nearly empty tank, something which is not recommnded.
