Why is this not litter?

So on the way back from lunch at Casino el Camino yesterday, I saw this on the dirtiest, stinkiest, most disgusting sidewalk in North America (6th Street, Austin, Texas) and see this.  If it were a Pepsi top, I think the same old thought would come to mind:  “People are thoughtless pigs, littering on my street.”  Maybe even if it were a Budweiser top.  Maybe. Definitely if it were ANY light beer.  But Coke has brand power with me like no other.  I wonder why.  Because I’ve never, in 44 years, had a bad experience with it?  Or maybe I have, and it still didn’t prevent me from buying it again.
