It's worse when that stranger is also surreptitiously filming you to paste it all over the net as evidence of how 'kind' they were to you.

What a weird straw man; he did not hand her trash, he handed her flowers under the guise of doing him a quick favor, then ran off. I guess she could think of it as trash after he left and even if she did - you genuinely wouldn't think some random person handing you their trash is kind of a rude thing of them to do?

Sure, but I'm the kind of person who picks up litter anyway.

That's great, then it sounds like we're on the same page.
