For those who are bothered by the biryani conversation in the video, it was probably a lighthearted humorous exchange between the two folks, do not take it literally. It is common for people to talk that way, especially meat lovers, who are abstaining from meat, they just refer to what they have on their plate e.g tofu or soy as meat, just to cheer themselves up. Most Importantly, thank you Mr Richard Goh for this high quality presentation, great work!
