A 5 hour service is hardly that long. Many shuls are notably longer. We’re you expecting to be in and out in three hours??
It’s not a race, but we finish in about 4 hours – 0700 to about 1100. And yes, 5 hours can be long if the davening is shlepped out for no reason – long mi shebeirachs, chazanut that goes on and on without end, a rav that falls in love with the sound of his own voice and drehs on for 45 minutes or an hour . . . I’ve been there and done that. I feel your pain, Yussel.
