Enable the money, in my opinion there must be. Why so if one wants the petrol script. If you can put it on and make gasoline and say you have no money, or something else. In my opinion, the money should be activated!
There are people who don't like going there for gas. But you could put the option Enable / Disable this thing 🙂
Sorry if my english was bad but i'm using google translate and i don't know english well.
