A lie. I have literally my entire adult life lived walking distance from the grocery store and I've even walked to the grocery store and I have always shopped weekly. Being able to cook daily is a luxury of time and energy. I don't bulk buy, but I definitely only have a weekly pit stop. It's not as cumbersome as the person you're replying to thinks. A week of groceries is only like 3 shopping bags, but still it doesn't make financial sense to go grocery shopping literally every day. Buying tiny amounts of groceries just doesn't make much sense with how things are sold, especially if you're a single person.
