Did Alma really wait until after eating to tell Amulek who he was? Alma 8:23

Alma goes on a mission and gets a lot of rejection in a place called Ammonihah. He's commanded to turn around and go back and preach repentance to the people, Jonah-Ninevah-style.

He's tired, depressed, and really hungry. He approaches a man and asks him, "Will you give a humble servant of God something to eat?"

That person was Amulek. Alma probably didn't know it then, but Amulek had seen Alma in a vision and been commanded to receive him, feed him, and listen to him.

Answer:
I bet that Alma's story probably did mostly unfold after the food was consumed, but it doesn't seem that likely for him to wait to completely disclose his identity. But hey, maybe they had weird eating customs where like, you weren't allowed to talk and eat or something. Or it was rude to talk with your mouth full or something.
