Final answer:
You should wait until After the service before discussing your retail product recommendations.
Step-by-step explanation:
You should wait until after the service before discussing your retail product recommendations. When providing a service in a retail environment, it's important to focus on the customer's immediate needs and the service being provided. Discussing products too early can seem pushy and may make the client feel uncomfortable. However, after the service has been completed, you can use the opportunity to recommend products based on what you've learned about the client's needs during the service. This allows for a more personalized recommendation and doesn't disrupt the flow of service.
