A customer at a vet clinic could be unhappy for a number of reasons. It's up to you to resolve any mistakes within your power and appease the customer to keep them coming back. In your experience with customer service, which skills have helped the most? Listening is the best place to start. Sometimes all your customer needs is to express themselves.
