Germans NOT So Environmentally Friendly

When Taiwanese talk about Germany they often think of "clean country" and "environmentally friendly". (Other adjectives are serious, well organized, little/no humor). That was also what I thought I remembered about Germany, and I thought it was even getting better and better. And now I have been walking and cycling through Stuttgart and I saw this (not just in one place/not just in a isolated incident):

I guess I have to appologize to my wife, after complaining so often about environmentally unfriendly Taiwanese. And I definitely will get something to hear when she sees this.
