I used to feel this way untill I became good friends with a Sr. Porsche Mech at a Dealer.

So as mentioned above... Yes, it was 1.5 hours labor for you. ...but...

There is diagnosis time. They can't take your word for it. THere's no risk to you if you're wrong, all the risk is theres. So they can't take your word for it. There is no warranty when you do it. Finally the dealerships have other procedures prescribed by the manufacturer that they must do when they do a particular type of work. For example: When simply changing brake pads they might also have to clean calipers, bleed the fluid, check the dust boots, lube sliders, check brake line condition, etc... Many other procedures outside of just swapping a pad.

...and for every job that's 3.0 hours book that takes them 1.5 hours, there' another one that's 3.0 hours book and takes them 6.0 because bolts are frozen, other shtuff is broken around it, screws are stripped, etc...
