Is this an "quantum mechanic" example?

I’m wondering if this guy is a “quantum” mechanic. He must operate on the uncertainty principle, because on a given day it is uncertain whether or not he will show up as expected. He’s had my car up on blocks (zero kinetic energy) in my driveway for about 6 weeks now, and he has been a n-show for about 24 hours. He’s a good technician, and definitely knows the ins and outs of an auto engine but very much like the Schrödinger’s cat, I have to wait until he either shows up or does not in order to know if the job is going to be finished today.
