I sat next to him and watched the whole thing and found it hilarious. Had to convince him he wouldn't seem extremely impolite if he appeared to change his mind a ask for a sandwich anyway.
Before he learnt to speak English very well, we went to a lindy hop course together. There he saw this beautiful woman (he was a widower), went up to her and said to her what must have been a literal translation of a very nice thing to say in farsi:
"You move and look like a very strong horse".
I showed wingman skills I never thought I had, and they are now happily married.
