Which of the following is NOT an appropriate finishing touch to your service?

Sending a postcard for helping with a gift is not typically viewed as an appropriate finishing touch to customer service. This option implies a focus on an external action rather than directly reinforcing the customer relationship. While it may seem thoughtful, it doesn't directly contribute to the immediate customer experience or facilitate continued engagement in the same way that the other options do.

In contrast, reaching out to customers for feedback shows that you value their opinion and are committed to improving your service based on their experience. Sending a handwritten thank you note provides a personal touch that can enhance customer loyalty and satisfaction. Giving your business card and encouraging returns not only fosters a sense of connection but actively promotes future engagement with your services. These actions all directly tie back to the customer, creating a more personalized and lasting relationship.
