Where does Hastings run into Poirot?

Hastings runs into Poirot at the post office.

As we drove through the village, I remembered that I wanted some stamps, so accordingly we pulled up at the post office.

As I came out again, I cannoned into a little man who was just entering. I drew aside and apologised, when suddenly, with a loud exclamation, he clasped me in his arms and kissed me warmly.

“Mon ami Hastings!” he cried. “It is indeed mon ami Hastings!”

“Poirot!” I exclaimed.

I turned to the pony-trap.

“This is a very pleasant meeting for me, Miss Cynthia. This is my old friend, Monsieur Poirot, whom I have not seen for years.”
