Go to the scene in which Jake is about to give his farewell speech in the synagogue. At the beginning of the scene you can hear a cantor singing the "Kol Nidre" prayer. While the cantor is singing people are mingling and chatting.

Kol Nidre is considered to be the most sacred part of the most important holiday on the Jewish calendar. There is NO WAY anyone would be talking. To those who have never been to a Yom Kippur service this may seem like nit-picking. To those who have, however, it's a major error.
