As a Vietnamese, I feel extremely sorry for you and I apologize for my country's behavior! At 12:06 I was able to hear some of the Vietnamese words: "Nó muốn ngồi trong thôi" -> "She just want to sit on the inner seat" I think they were mistaken due to the guy who sat first on your seat 😢 (Sorry for my bad English!)
I don't think there is much of it in Vietnam, but the world is a country of racism. 🌏🇻🇳 Women face discrimination depending on the country. You are amazing.😢
