One afternoon, I had to take a regional train to visit a nearby town. The station signage did not make sense to me and I suspected I was waiting at the wrong spot. I saw a couple of local women waiting there, and that reassured me at first. Surely, they knew what they were doing.

But after a short while, and seeing as my suspicions did not disappear, I decided to approach them and ask.
>sumimasen. eigo dekimasuka?
When I walked towards them I could see they were startled, but as soon as I said "sumimasen", they visibly relaxed.
>dekinai!
One of the women almost proudly declared she did not, in fact, speak English.
I proceeded to try to communicate my worries to them in very broken Japanese and a lot of gesticulating and pointing at my and their tickets, and they assured me we were in the right spot. However, as the time for the arrival of the train approached, reading some signs with the aid of Google Translate I was almost sure we were not at the right spot, so I tried to make them know.
It turns out we weren't, and thanks to that interaction we avoided missing the train. They tried to strike conversation with me, but I completely dropped the ball and they probably thought I was being rude or uninterested, because we ended going our separate ways. I probably gave them the wrong non-verbal cues, but I did my best (another thing I noticed is that they are very perceptive to this kind of thing; picking up on subtle body language and running with it).
