I'm always confused by how to say excuse me in Korean. I first learned to say "silehamnida," which is described in the first video on this post. But people look at me a little funny sometimes - and some of my friends told me that this is pretty polite and that there are more common ways to say this in everyday settings.
So, I'm so happy that I found another video explaining two different scenarios in which you might say "excuse me" - both of which I've used A LOT. Asking people to move aside (crowded buses and subways!) - "chamsimanyo" - and getting a waiter's attention - "chogiyo". You have to watch this video. This guy Justin is HILARIOUS. He even cracks himself up, and the video person. I can't wait to see some of his other videos!
The contrast between these two videos is pretty significant (that's an understatement!), but they are both useful. Enjoy!!
