Apushutayid – “At least they “chap a minyan” on the bus”
That’s the point. Minyanim aren’t really supposed to be “chapped”. I can’t tell you how many times (virtually daily basis) I’ve seen impromptu minchas and maarivs “chapped” on the bus, disturbing everyone else around them, when mincha or maariv could easily have been davened properly in a shul or shtieble once getting home.
While we’re on the subject, why is it that mechitzos are put up for shacharis, but not for mincha & maariv? Food for thought.
