On the issue of people using other languages to talk about one another: Most of my friends in college were from other countries. My best friends were from Curacao & the average high school dropout down there speaks 4-5 languages. My friends, all guys, mainly spoke Papiamentu & Dutch. I had to get used to it, but a few times it did get on my nerves, mainly when I was hormonal.

However, it taught me a lot. When people who speak a common language are together, it is easier for them to just fall into their native tongue. Of course, they were guys in college and 99% of their conversation was about girls. When I learned to speak Papiamentu easily and then learned to understand Dutch, they swore they were going to have to make up a language that I couldn't speak. I already understood French & spoke Spanish and they could not fall back on those.
Whether or not people are talking about us in another dialect or language, it is totally our ego that assumes so, pretty much all of the time. Yes, there might be bored employees who use their language as a way of entertaining themselves during a long day of sanding people's feet... If I were in their position, I might be doing the same thing. We claim people are rude but we don't look at the rudeness of our assumption that we are "so important" that they are secretively talking about us. Tambien, quien sabe y cual es el problema?
