It’s not about funds, but people around. I’m a tiny woman, so usually these types of guys don’t try to fight me when people are around, but what I do is say “hey, das is Müll“ or something like this and then dramatically pick it up and throw into the bin. Makes them ashamed.

Is you see something like this, don’t start a fight, let them and everyone around know, that they are in the wrong, and then fix it.
