By all means vote for this closed if it is not your experience (and therefore "opinion based") but why do shuls not announce which directions in which order we shake the arba minim according to the shul's nusach? Like we have a few announcements before shofar explaining the halachot as well as local Minhag, but when it comes to this i.e. Arba minim, it seems in all the dozens of orthodox shuls I've been to, there is no announcement but everyone still manages to collectively settle on a certain order together..
It's not something like a sefardi Ashkenazi divide that I am simply being "dyslexic" about either. I've been in many of both, and the nusach varies unpredictability even within these broad categories.
I somehow suspect this is a good "homework" question that might get some essays as answer (or not), either way I hope it's an interesting question to some degree! I am not really in the world of gabbaim and organising a service so if it's a very simple and clear answer I also won't be shocked!
