I would hope the mechanic would engage with the customer in more back and forth.

But sometimes power structures don't allow for it. I worked tech support in a number of companies. At some companies we were empowered to investigate and solve problems... sometimes that took work, and work from the customer. It had much better outcomes for the customer, but fixes were not quick. Customers / companies with good technical staff in management understood that dynamic.

Other companies were "just fix it" and tech support were just annoying drones and the company and customer's and management treated tech support as annoying drones. They got a lot more "you got exactly what you asked for" treatment ... because management and even customers will take the self defeating quick and easy path sometimes.
