Jerks who let "Fluffy" out of the pet carrier and let them wander in terminals (either on a leash or not) without paying any attention to numerous announcements to the contrary. I can't stand self-entitled a-holes who think rules are for everyone but them. It's even worse when it's middle-aged couples with children. Thanks for teaching them to do whatever they want, wherever they want.

We all know that if "Fluffy" pees or craps they'll just walk away like nothing happened to let someone either a) clean it up or b) slip or fall because of it.
