What is a sign of suspicious activity in trends?

The option indicating that the same person is repeatedly opening and closing the register is a sign of suspicious activity because it can point to potential manipulations of sales transactions or cash handling. When one individual has exclusive access to open and close the register, it creates opportunities for misappropriation or fraud, as there is no oversight or accountability from other employees. This practice disrupts the checks and balances typically necessary in a retail environment, allowing for irregularities in cash flow or transaction reporting that could go unnoticed. In contrast, excessive discounts for regular customers, multiple employees across different shifts, and manager overrides on sales can all be part of regular business operations, albeit they may warrant monitoring to ensure they are not contributing to loss or fraud.
