You are an employee for a small jewelry repair store. Over the past few months you have noticed that business has been slower than usual. Fewer repair orders are being taken and you receive fewer phone calls asking questions about the services you offer. You suspect customer retention has been affected by some outside influence or perhaps by a change is service quality due to a new apprentice working in the shop. 

How would you determine the reason for the loss in customers? Design a brief plan to determine customer satisfaction and suggest a possible customer service plan to counteract this trend.
