I Agree with you till this point …. A SHUL IS MEANT TO DAVEN IN yes and people that come to shul and mumble to themselves the davening! that’s not the proper way of tefillah. PSDZ till shema and tefillah is supposed to be BEKOL ROM. If it bothers you that means you are not davening. Se haist nisht gedavent
Jewish Source, can you please tell me where it says this? What is the actual inside source?
