1. Beis Shamai: Each person should make the blessing on fire for Havdalah on his own, in order that people not have to interrupt their learning for an extended period of time. Beis Hillel: One person should make the blessing for everyone because of the concept of "b'Rov Am Hadras Melech."
2. Doing so will cause constant interruption of Torah learning.
3. If he mistakenly forgot to recite Birkas ha'Mazon where he ate and it is difficult for him to return to that place, he is permitted to recite Birkas ha'Mazon in his current location.

5. Even though the person who answers "Amen" is equal to the one who says the blessing, the one who leads the blessing is answered sooner.
