I can confirm that. The cultural attitude in Germany is that food should not be wasted. One of my favourite café bars in Heidelberg, when it closes, gives away the unsold pastries to the people who are still there -- sometimes a whole bag full.
There are still a lot of Germans around who remember not having enough to eat as children in the late 40s. Yes, their parents had done, or at least allowed, terrible things, but they were children. Meat was especially in short supply, and my 85 year old aunt-in-law is pretty sure they had rat a few times.
So my elderly German in-laws would be horrified with how casually my Texan ones will buy and grill large, expensive slabs of beef, and end up throwing out a good deal of it because it was way more than the bunch could eat. I am, anyway, but have learned to bite my tongue.
Can confirm, my parents grew up starving in the ashes of WW2. My mother hid canned food under her bed, in her closets, everywhere for all of her life. It always annoyed me and when I'd ask her about it she always answered the same, "I hope you never know what it's like to starve".
