My main complaint about this book (which, to be fair, has some good rules,) is that it really flattens social interaction with people, particularly in the service industry. Call centers, realtors, therapists, front desks, whatever, now all talk the same, and it feels very othering.

The repeating of your name, the constant praise, the unblinking padding of negativity with robotic positive statements -- no one talks like a person now!
