Let me rephrase your post.

Your parents decided to open up a coffeeshop in a town with limited customer potential on the other side of the country. They have no experience in the industry and rely on you for the day to day operation. Since the business is failing (no surprise there) your dad spends a shitton of money on stuff to expand the menu (read: adding additional operation costs) without doing research to justify adding these operational costs.

Your 6 months in and the owners still don’t know the menu and depend on you. So basically you are the business but without the ownership and the money is controlled by a guy who actively makes it harder for you to succeed.

Not realy, they where artificially lowering the cost of a fair (for a while). They did so by investors funding it, drivers not having the propper insurance and depending on location they themself breaking labour laws.
