Burger Shop is a casual time-management order-filling game that was originally a PC exclusive before getting several mobile ports six years later.
Unordered Food Items
Food that can be made by the player, but are never ordered by customers.
Present in the game's image files.
Possibly intended as an alternative to Chicken Nuggets and Vegetables, as its sprite rotation suggests it could've been used for the Food Tray item that the Chicken Nuggets and Vegetables also use.
Single-Unit Patience Bar
In Burger Shop, customer patience is visualized by a bar with circles indicating how long a customer will wait for an order. Present in the files is a sprite for a one-circle patience meter, though no customers in-game have this little patience (the closest is the Punk, who has two units of patience).
