There was a client that I had that had a language barrier because he had a thick accent and it caused him to become very frustrated and very irate at times because it was hard for us to communicate. So instead of him trying to communicate with me in English, I downloaded an app and kind of brushed up on some of the basic terms of his language so we can have a better rapport when it comes to speaking with each other and he would have a better understanding of what I meant and I would have a better understanding of what he meant.
