Currency

Currency in Cooking In The Rain is divided into Two Main Currencies, those being "Coins" and "Gems". Coins and Gems both are unlocked by either serving Customers/Diners, or by completing a quest.

Coins
Coins are used as the main currency in Cooking In The Rain. They are used for everything shop related, such as Upgrading your Stall, purchasing Pets, or buying decoration. The main source of income will be coming mostly from your Customers, or the ones at the Diner. Additionally, coins can be bought for Robux, costing 100 Robux for 5000 Gems

Gems
Gems are more of a "Special Case". Rather then Coins, Gems can only be obtained through either serving a diner customer, or by completing quests. Gems can be used to either buy special decoration, or to buy the third food stand upgrade. As well as coins, Gems can be bought with Robux too, costing 80 Robux for 20 Gems.
