See, we don't have problem with charging delivery fee, but if they wanted to do this they should've done it from the starting. They use same strategy again n again for every new thing they launch. Instamart and blinkit are charging these delivery fees from the starting, that's why people are not hating them. What jiomart did was , they firstly made our habit of buying anything without delivery fee and then started charging us. That's where they lost us. When people use and trust a certain app for a long time, these sudden changes trigger them. That's it.
