What happens if you use 반말 to a stranger?

Have you ever mistakenly used Casual Speech, when you were supposed to speak politely?

I met with Korean Arah and we discussed what would happen in these situations, as well as why it’s important to know the correct way of speaking.

Special thanks again to Korean Arah! Make sure to check out her web site for learning Korean, which I’ve linked in the video’s description.
