Thanks for playing!
During daytime, you can open the item menu and drag items you've purchased onto the customers to give it to them. Some items only work on customers of a certain color, such as hot dogs for red and broccoli for green. Other items boost their patience, speed or tip in a positive way. Some items can only be applied to stations..
Unfortunately, we didn't have time to properly explain the system in-game so it's a bit of a guessing game. Only Lumie, who designed it, understands the mad depths of the system. It is possible to chain items such that a customer stays in the shop for ages, exponentially increasing their tip. With that it's possible to 100% the game in 5 days.
