When we were on holidays last year, we decided that, rather than have our final meal early and then travel to the town where the airport was located, we would travel first and then have our meal. So, we found this café near to where we parked, and ate there. We were the only customers, and had a good conversation with the staff.
This year, we went back to the same place, and things had changed. For a start, rather than having 1 café occupying 2 units, there were now 2 smaller cafés side by side. Only one was open, and there were quite a few customers. And EVERYBODY in there (staff and customers) was chatting away to each other... in Russian! (Yes, even the local woman who was serving the food was speaking Russian).
Anyway, by the time we were finished, all the other customers had left. The local woman who was doing the serving had gone to the shop next door to get some change, so it was the cook that we paid, and said goodbye to.
It was obvious that the cook was Russian, so when she came to say goodbye to me, I said "spasibo". And her face just lit up, and she started talking away to me in Russian. And because "spasibo" is about the extent of my Russian, I hadn't a clue what she was saying! So I just smiled. It was so embarrassing!

:
To further add to the embarrassment, I then left my sunglasses behind, and she came running after me. But, I didn't make the same mistake of thanking her in Russian. This time, I said "Oh, thank you so much!"
I really need to learn more Russian...
