TIFU by telling a bunch of Polish Govt Officials that I'm a spy from the USSR

I'm a student on a gap year working on a start up. We basically provide ESL classes to foreigners by connecting them with a certified pen pal from the states. After a long series of bureaucratic hurdles, me and some of the other lads working at the company managed to travel to Europe to promote our app.

The first stop of the tour was Poland, where we managed to get a meeting with some representatives from the government who wanted to use our app to train some potential diplomats. Poland was awesome, beautiful country. I recommend visiting Krackow, the captial.

Anyway, our meeting was in this weird looking room that was kind of like a classroom from the 70s. Me and the lads from the company stood at the front of the room while the 3 government officials sat in plastic chairs and listened eagerly. They spoke English, though not perfectly and with heavy accents.

At the end of our presentation, we opened the floor for questions. The official in the middle, a scary looking guy with a black moustache asked: "This SR [name of our app, SpeakRight] app is impressive. How you choose your 'certified pen pals'? Since we want use it for diplomats, we must make sure no American government influence on this process." Since I'm in charge of hiring, I took the question. I gave him the spiel on our application and interview processes, and the degrees we require.

This is where the fuck up happens: I then assured him that the US government would have no involvement with our app, and that I didn't even know anyone in the government. The way it came out was much worse, however. One part of what I said was: "The US and SR haven't sent any of us to gather any information." I got a weird look from the man with the mustache and then the three men started whispering to each other.

The meeting concluded normally enough after that, and we started to head out of the building. In the lobby, security guards intercepted us and brought us to a dimly lit interrogation room. It was like a scene from a movie-- I thought I was going to be beaten severely, but a nice looking man came in and said "Hello, we just need to clear a few things up before you can go on your way. When you said you were gathering intel for the Soviet Union, this was bad American joke, right?"

We looked at each other with confusion, then a light bulb went on in my head. When I said "The US and SR haven't sent any of us to gather any information," the men probably thought I said "The USSR has sent us to gather any information." I explained to to the man and he began to crack up laughing. He brought in the men we were presenting to, who laughed and apologized.

We ended up signing the deal, our biggest yet, and now we have a story to remember.

TL;DR: Accidentally said I was a USSR agent to the Polish government and got interrogated
