What I think you are not taking into consideration is the fact that this started with a phone call.
If someone called me and said "I wrecked my bike and I need an estimate how much would it cost?" I would reply 2 hrs.
That being said once I have the machine in my shop the price may go down. If the damages are superficial and cosmetic only, then I would not charge the full two hours labor. However, you must be able to look at the opposite end of the spectrum. What if what the customer says or thinks is "nothing major" turns out to be something major once we start pulling the bad pieces off and digging deeper into the damages? At this point you could spend well more than two hours looking everything over. However, my cost would never exceed the original quote of two hours labor.
All I am trying to get someone to see is that this guy threw in the towel and bad mouthed this dealership before really giving them a real chance to prove to him that they arent out to screw people over. I am not affiliated with them and I can only hope that they are providing a proper service. I am atleast willing to give them the chance to prove me wrong before I base my whole opinion on a phone call.
Think about this:
Calling someone on the phone for an estimate like this is like asking me how many bubbles are in a bar of soap.
I have no way of knowing until I see it for myself!
