As a delivery person, you can ask customers for positive feedback in the following ways:

Provide excellent service and food: First, you need to make sure that the quality of your service and delivery is excellent, which is a prerequisite for customers to be willing to give positive feedback.

Thank customers for their support and trust: when you deliver the food to the customer, you can politely express your thanks to the customer so that the customer can feel your sincerity and honesty.

Remind the customer to give favorable comments: In the process of delivering the food, you can appropriately remind the customer to give favorable comments, but do not be too forceful so as not to make the customer feel uncomfortable.

Offer discounts or incentives: You can include coupons or small gifts on the delivery box or tableware to incentivize customers to give positive feedback.

In short, a delivery person should base on sincerity, politeness and quality service, and guide customers to give favorable comments through appropriate ways, and at the same time, need to respect customers' wishes and choices.
