DM's who want you to Roleplay but can only say "No."

[Milo v3]

I've been in situations where players essentially say 'Bow before me, for I am High Lord of Something, and kiss my feet. Else you suffer', and keep true to their promise. It is realistic, but...

Has any one encountered this kind of DM?

Yeah, I didn't last long in that game though (in-character and out-of-character).
