Stopped at Incheon with my son and the staff was VERY obviously talking about us in Korean and chuckling as we passed security. This is rude Asian behavior (I grew up in another Asian country, and this is something I see Asians do quite a bit) and in 2020 should no longer exist. Retrain your staff and end what we Asians have become infamous for. I'm literally embarrassed to be Asian when I see other Asians behave this way. Disgusting.
