I recently prayed mincha on a fast day where no talis was present. The kohen present did not bless us, since he could not cover his hands with a talis. (No one called him to do so, so he wasn't in violation of refusing to bless when called to do so, which I understand is the main problem with not blessing. Still, had there been a talis, he would have blessed.) What should he have done?
- Not blessed us.
- Blessed us without covering his hands.
- Covered his hands with something else and blessed us.
- Something else. (What?)
