#2 just an FYI Setup is NOT done by the wrench. It is done by the assembly guys. These are the lowest paid workers in the shop. They simply go by a sheet of the steps needed to uncrate the bike and set it up.
The man with the wench may make sure all the updates are done and just check it out right before delivery but that's it. The shop will not pay the lead guy to set up the unit it would be foolish and if so none of us would get our bikes fixed when they mess up. Whyis this because the shop needs to make the sale and get the unit to you, and we all want our oil change done yesterday .

It is the same with cars a get ready person will set the car up and get it out to the buyer not the mechanic

I had a bike delivered with the front wheel on backwards before

I do agree you need to pick a shop that has a good rep for repairs made Sometimes that means you buy from one dealer for the sales amount and use another for the repair

but your info is great otherwise
