Wow interesting, in my country we hardly see that but it would make the hassle of being in the supermarket choosing product by product much easier. Only once I asked them to bring me groceries from the supermarket and the truth was very good, I personally see it very useful. Yes it is true that human beings increasingly find ways to not do what we should do, but at the same time this helps to generate more jobs like yours which I find fascinating. Good job ✨
