Per household or purchasing body (as in a store or restaurant) I have my doubts. Never in my life have I dumped 3 dozen perfectly edible sandwiches in the trash on any given day.
There are a lot more households than there are stores or restaurants so in aggregate total homes may make for a greater sum, but that’s the same kind of logic they use to say people need to all switch to paper straws and forgo the AC in summer while the rich fly about in personal jets and rockets for a joyride.
People have done that for ages. Pic taken of the screen with another device, try and block that now. Basic rule, if you send it out assume it’s no longer private.
