"Embarcadero, 5 minutes"

Nathan and I went on a walk today after I got back from work.

As we walked past the N-Judah train stop, I heard Nathan say something about "Embarcadero."

"What?" I asked.

"Embarcadero.  5 minutes!" he replied.

Apparently he had overheard someone mention that the "next train heading towards Embarcadero (a train stop) is arriving in 5 minutes."
