Some people don't need to be seen or heard.
We almost put Carrie from On the Fly on this list for battling with airline employees who made her buy a second seat because they had "assumed" she was a customer of size. "I'm not even overweight, it's just baby." Unless she's the next Octomom, we can assure her it's not all just baby. But delusional isn't necessarily heinous, and she did end up buying the extra seat, so let's move on to people who were really awful.
Guess these people didn't think being decent was their patriotic duty this week.
