I got a good idea from watching your vlog video about the red flour bread shop at Jelkhana Mor in Bogra. This arrangement of healthy food at low cost for the common man is really different. Although the shop is not as clean as a restaurant, seeing red flour bread being made in front of your eyes and its nutritional value is very important. The way you have highlighted the profit and loss aspect of the business by calculating 40 kg of flour shows that you have observed the matter deeply. Getting 300 grams of red-flour bread with free dal-bharta for 30 taka is quite affordable for the common buyer. I think that consuming such nutritious local food is much more beneficial for health than the delicious but unhealthy food of big restaurants. The experience of eating while watching the visual cooking process always gives a different satisfaction. Best wishes to you in this contest. 😊
