100% of the time. Like, no one player ever leans over to another player and says, "Can I get you some coffee?" or "Did you take that spell when we levelled?" or "This is too easy, I think the DM has a trick up their sleeve," or "Nice roll!"
I am not doubting it, and definitely do not disparage it, it just seems hard to comprehend.
As far as I can tell from people who've indicated all discussion is done in-character, there's a physical tell if you need say something OOC--raising a hand or turning a cup in front of you upside down or some such.
Since I play primarily in third person its never been something I've seen in person (I'd be as welcome as sunlamps at a vampire convention), bt I also gather some simply physical reactions aren't treated as part of it (laughing at something some other player's character does for example).
