Facepalm

I used to work in HR. In my first week, the HR Manager walked around with me on the floor of our factory. We had a lot of Vietnamese employees. She wanted me to start learning people's names, but the first time we encountered a Viet person she whispered to me "hey, between you and me, I can't really tell them apart since they all look similar and have similar names, so if you can't remember them then it's no biggie". Like what??? Ma'am you are the HR manager.
