I can cook quite well but honestly living in NYC and going to the grocery store to serve my partner and I ~2 meals a day every day of the week is nearly impossible with our work schedule. If I wanted to do nothing else with my day but work and cook, that might be fine, but Doordash et al. are making life a whole lot better. When we were launching our company, we joked that it was often just a stream of delivery drivers bringing us stuff to sustain ourselves.
