give the guy a break, atleast he fixed what you wanted, nobody is perfect
and if you know so [censored] much about all this, how come you are not doing it yourself? The only way to be 100% sure everything is to your satisfaction is to do the job yourself....
I do everything on my car from oil changes, to tires, alignments, to engine swaps....... its a nice feeling knowing you keep it running yourself and don't rely on other people
