This isn't cool. A woman was travelling thru DIA last week with her dog. At one point, the dog poops in the middle of the floor and when someone pointed it out to her, she flipped him off. She was on the phone at the time, so HOPEFULLY she cleaned it up after she was done, but the video doesn't show that, so who knows.
If that were me I would be SO embarrassed and rush to clean it up right away, but she seemed a little too preoccupied to care.
