The push to finish fast is strong, but what's the point if the car comes back? Taking a little longer to do it right actually saves time later, don't you think?
Tell you what, watching a car swerve down the road because someone cut corners is its own kind of comedy. Guess that's what @nancythomas means by "fast," maybe they skip the machine and just eyeball it. Sure saves time until you're replacing a whole set of tires next month.
