I don’t leave early, but often come late, so I usualy switch rooms to a differnt minyan, so I can catch what I missed in the one that I picked up in middle, and then leave once I’ve filled in all the gaps (Example: I’ll hear kriyas hatorah at the 6:15 minyan, and then leave right before kriyas torah of the 7:00 minyan)
But for the folks who do leave early, this morning, could have been one of mine. I davened at a minyan with a bal tefila whose voice roller-coasted (loud/low/on tune/off tune) and to my right, was someone who felt necessary to SHOUT his way thru davening.
If ever there was a time that I would have left early, this would have been it. I’m a pretty patient guy, but whose to say what anothers patientce breaking-point is?
Don’t judge another for leaving early.
