Okay, let’s tackle this. So Robert Virovatz has 51 years of experience as a Service Engineer, which is extremely long-term. This level of experience typically translates to high expertise. Location is Milwaukee, Wisconsin, which is a mid-sized city in the US. Industry standards for Service Engineers with his level of experience suggest a lower rate, possibly around $75-$100 per hour, considering the industry average for long-term Service Engineers in the US. This estimate is on the lower end, but it's reasonable given the lack of specific skills or qualifications mentioned.
