For 1, I still have yet to go to a restaurant where I couldn't ask the waiter for a physical menu instead of reading the QR code (not to mention that QR code menus are still far from the majority in every city I've been to, small and large). Are there any other examples where you "need" to be online when going out?
For 3, I've never been to a supermarket that doesn't have fresh local produce. The existence of a ready-made meal or of a more complicated snack food doesn't make produce in the same store any less real.
