if One misses barchu bc he’s late for maariv, is it important to say it afterwards like they do an EY? Or there’s no real obligation to have to say it. I came late and after maariv someone asked why I didn’t say. what is the reason for saying it in the first place if you missed it?
In the Rabbi’s shul the Chazzan says Barchu before Aleinu. So not relevant.
I asked around a little and if I got the right message, the Rabbi’s opinion is - it’s a nice thing to do but not required. Reason being - Why not get another Barchu in there. It’s a Davar Shebikdusha.
