As cool as this is, the sad part is that we know this asshole most likely threw the trash out again and the guy had to sweep it up again.
I had a similar incident like this once when I owned a convenience store. I sold a guy a sandwich and some chips. He sat in his pickup truck across the street from the store to eat his lunch and I saw him toss the sandwich wrapper out his window. I casually went out and picked it up as he was talking on his phone. I tossed it into the bed of his pickup and I don’t think he realized it. I figured he’d get out and just throw it out again, but at least he’d have to do that. I don’t think he saw me do it so he drove off with his trash. A small victory, but it felt good to do that.
