What action should be taken at the end of the day regarding checks?

At the end of the day in a retail setting like Costco's Optical Department, the appropriate action regarding checks is to pick them up and take the register to MIMO. This procedure is essential for ensuring financial accuracy and accountability.

MIMO, which typically stands for "Money In Money Out," is a system used to track cash transactions and manage financial records efficiently. By taking the register to MIMO at the end of the day, you are facilitating a secure and organized process for reconciling the transactions that occurred during the day.

This action helps maintain the integrity of financial records and ensures that any checks received are properly accounted for in the company's financial system. It also provides a safeguard against mismanagement or loss of funds, as the checks are handled in a controlled environment where they can be logged and processed according to company policies.
