As someone who worked an MK attraction during his tenure, where I and a few others said hi to him when he went into our attraction, he literally said the words, "You do not speak unless spoken to." He is directly responsible for lots of mismanagement throughout the park during his tenure that other area leaders that have come in after have had to clean up. If MK CM's had a positive opinion on him, he wouldn't have earned the nickname Skeletor throughout the parks.
That should say everything. (Fun fact: Chapek also did the same thing to CM's during the opening of the Skyliner. His wife, however, is much nicer.)
