Can't believe I forgot a gross one that happened recently. Called over a TM to look at it, just because I could hardly believe it. Found what appeared to be an already worn sanitary or bladder protection pad behind cans of men's shaving cream. I say "appeared" because there wasn't any visible fluid on it, but it was creased in a way that looked worn. So someone pulled it out of their pants while in the aisle and placed it where it wasn't easily seen? Alternatively, they removed it while in the family restroom by the pharmacy and, instead of throwing it in the trash can right there, brought it out to the floor?
People can be so disgusting.
