Final answer:
The cashier must have another employee process the purchase of the soda, using her own non-transferrable discount card. She must pay before consuming the soda and cannot leave the store without paying for the goods.
Step-by-step explanation:
According to the Personnel Policy, the cashier at Walbound should adhere to several stipulations when paying for a soda. As employees cannot ring up their own purchases, the cashier would need to have another employee process the transaction. Additionally, the discount card that the cashier uses for the 20% discount is non-transferrable, meaning only the cashier can use her discount card. Also, the policy dictates that she must pay for the food before consuming it, ensuring that she pays for the soda before her break. Lastly, it's important that she follows the policy of not leaving the store with unpaid goods, which reinforces the importance of paying for the soda upfront.
