REALLY? Do ANY Chabd shuls cater to ANY other customs/practices of other Yidden mispallelim?!
Example; Do they sing Akdomus (which is in the Nusach Ari Siddur but not said)? Do they say V�Shomru Frinday night (again it is in their Siddur)?
Absolutely, if there are enough ballebatim who want it. Anim Zmiros too, if there’s enough demand. I’ve never heard of a Chabad shul that has leining on ST night, but that’s not all that common a custom, so there’s unlikely to be much demand for it.
