The best service technician is a service technician who is methodical. By this, we mean that they are focused on the task and literally start with one piece of furniture and then move to the next and the next, until they are done. In the kitchen this means pulling out kitchen drawers, stoves, fridges, and dishwashers. It also means inspecting kitchen appliances such as coffee makers, microwaves, and toasters, as they could potentially harbour cockroaches.
