I mean, not to be overly snarky myself, but it seems you felt this was a burn, when it gets at what makes 5E an amazing experience.
Player: "Can I do [X]?"
DM: "You can certainly try. Roll a d20 and add [Y]"
Not a burn so much as how it feels to me. "The GM can decide you get to do something if he feels like it" has never been decent substitute for, you know, mechanics as far as I'm concerned.
