Final answer:
It is appropriate to help a customer by looking after their items if it aligns with company policy and doesn't interfere with job performance. However, consider the potential liability and ensure items are kept in a secure area.
Step-by-step explanation:
Whether or not you should take responsibility for looking after a customer's items such as a phone and wallet when asked varies based on company policy and the specific circumstances. In many service industries, employees are trained to assist customers with reasonable requests to ensure a positive client experience. If company policy allows for it and ensuring the security of the items does not hinder your ability to perform your job duties, it may be appropriate to help the customer. However, it's also important to consider the potential liability if the items were to be lost or stolen while under your care. It's best to secure the items in a safe area, visible to staff but not accessible by the public, if you choose to look after them.
