I was on the jumpseat of a LCO's aircraft when I was at CATC (or whatever it is now)
The FO asked for a direct routing which would take us outside CAS, and was told that a RIS would apply.
He turned to me and said
"To be sure, we're meant to get a RAS, so we are, but there's !!!! all up here"
Shortly followed by a sharp left turn.
