Mechanic last remaining profession that can legally roast clients

"Why the fuck'd you buy a Volkswagen?" Things got personal earlier today when Matt, 18, took his VW golf to be serviced at the local mechanic. However, as a recent p plater and car newbie, he didn't realise that insulting uneducated clients was mandatory for all mechanics. After criticising his choice of vehicle, the mechanic became visibly agitated as Matt attempted to describe the "humming noise" coming from the engine. The mechanic told Matt "that information does not help me at all champion, I'll have a look at it buddy". Matt questioned whether the $600 fee for a 1-hour service should have been discounted for the emotional abuse suffered during the process.
