I do not deny this may and probably happened few times at best.
There is this that you cannot differ sometimes new players outside of PVT marines, as even experienced players or those who atleast know what to do have tendency to not put their medals on.
Most of my yelling is reasonable and happens when people do some insane shit. I keep it IC and only IC. If a person doesn’t know what to do something and clearly states that to me (or it’s atleast obvious they don’t know how), I’ll be happy to help and teach them normally. You kind of treat game very differently when you’re already a Mentor for a long time (with a display of who is a new player) and just a common player.
Ultimately, I’ll focus to improve my patience when it comes to such situations, thanks for your feedback.
