am yisrael chai-
I like halacha riddles because they teach worthwhile info and count as talmud Torah.
I have no clue, but here are a couple of guesses:
1) Before Simchas Torah Mussaf, after someone has had a “few too many”, and needs to sober up a bit for davening.
2) One who has forgotten Havdala on Motzei Shabbos, and needs to make it later in the week without aish and besomim? (don’t know this halocha well)
If, as I expect, the above two answers are incorrect, can you answer the following:
1) Is it davka coffee? any drink? any food?
2) Is it davka Shemona Esrei or a full tefilah?
