Agree that, by most standards, aeros in the R2160 cannot be called extreme. However, I've had some passengers where even LAROSA was too much, and I had to cut the sortie short.
So far I have not yet have to mop out the aircraft, fortunately. But there was this one guy (ex-navy pilot, commercial pilot and sort-of my manager) who didn't want to call it a day when he'd had enough, because of some weird form of pride. He spent about two hours sitting in a corner afterwards, white as a sheet, before he was able to function normally again.
