Why I am asking: I was called up to read from the Torah. The Baal Koreh when I came there, said “Good Morning”. It felt wrong to answer him, just before opening the sefer to make the brocho.
The question: What do the sources say about whether it is allowed for the baal koreh to greet a person having the aliyah with a 'Good Morning' before the oleh makes his brocho and is it allowed for the oleh to respond?
My Question is not dependent on whether the oleh is wearing tefillin, see this question.
