A challenge based on the following items I found together at the side of the road this morning on my walk:

1) A smashed Dunkin'​ plastic cup marked "Drive Thru" and with a label indicating the order was no ice, original coffee, black, two additional espresso shots

2) An empty pack of sugar-free Trident gum

3) An empty box of over-the-the counter anti-diarrheal

What scenario would explain these three items being simultaneously thrown out a car window on a remote dirt road?
