Okay, let’s tackle this. So Alan Barnes has 34 years of experience in customer service, which is a long time. Typically, customer service professionals with this level of experience can charge higher rates. However, considering the industry, location, and role, I'm going to take a conservative estimate. Customer service supervisors with similar experience in the public sector might charge around $25 per hour. But this is a very rough estimate and may not reflect the actual market rate.
