1. Is it worth buying a coffee machine? Does coffee restore energy? if so, how much and is it more profitable than buying energy in a vending machine?
2. I recently asked about the prices of cassettes and their levels. To get money for a cassette, can you just sell it in a box to complete a task, or do you need to sell the cassette as well as other items?

1. If you have a lot of money, buy.  (39 energy)

2. The box is specially for cassettes. No need to sell in an iron box
