Every good service technician we have ever met hates walking back and forth to the auto parts department
. Working on cars is what they are paid for, not fetching parts. That is why we have refined the way the service and parts departments interact. Commonly used parts are stocked right in the service area - sometimes right in the technician's station. For parts that are not right at hand, technicians use an electronic ordering system, and in moments, the parts department delivers the parts directly to the technician. Bada bing.
