just because you have that option where you are does not mean everyone has that option. Different areas, dude.
Just like there is no such thing as a "pull n pay" junkyard near me.. customers are NOT allowed out in the junk yards around here anymore. I can not go find a car, pull the part I want and go pay for it. Nope.. have to go to the front counter, ask for what i need, wait for one of their employees to go get it (if they even have it) and pay premium prices for that privilege.
and there are very few shops around here that will do the kind of work you are suggesting anymore, either. That is just the way it is now.
Be grateful you still have that option, but also realize that not everyone does.
