Same person also did the installation instructions for Glacier Bay medicine cabinets. 3/5 and 2/9 were measurements I recently had the joy of running into.

I can say with 105.6% accuracy that I did not install the framing to the exact dimensions as specified. If Glacier Bay has a problem they can make tape measures with 1/5 and 1/9.

Situations like this are simple.

Employee: I haven’t been compensated properly

Employer: Usually some sort of bs.

Employee: I’ll let the labour board decide who is right.

It’s usually the end of it, as nobody want the headache. Because I work in construction the other go to is “should we call health and safety?” Puts an end to all shenanigans immediately.
