Restocking
There are two ways a shop can be restocked, the first being going into buy mode and deleting the sold out signs, to replace with new stock, or having a Sim restock themselves. Doing this means the Sim can earn a talent badge and the player can focus on other things, but it takes time. Like any other Talent Badges there is three to earn. Bronze, Silver and Gold.
The time it takes depends on the talent badge, with a Gold talent holder managing the task in seconds, and one with no badge taking considerably longer.
