A sweaty, greasy 40-something. A self-proclaimed veteran who tries to run the public platform like his own backyard. "It's always been this way" is his get-out-of-jail-free card. Both his attitude and body odor are overwhelming.

The stereotypical nerd in a plaid shirt and jeans. A man of sophistry who justifies nuisances with "What law am I breaking?" He looks weak but acts high and mighty. A walking internet comment section.

Silent when his friends cause trouble, but reacts instantly to criticism. A pro at dodging responsibility who can only say "Don't lump us all together!" His victim complex is the size of a bullet train.

16 years old. Manners and restraint not yet installed. He barks "Move!" at passengers, but pulls the "I'm a minor" card the moment he gets scolded. His mental age is even lower.

A 22-year-old rookie. Small and baby-faced, her voice still trembles when she's yelled at. Still, for the sake of safety, she stands up to the swarm of stench, insults, and excuses with a polite "Please cooperate."

29 years old, 7 years of experience. He hates these photographers. But since they're technically customers, he can't punch or scream at them. He bows to their garbage excuses and protects the rookie while saying "Please cooperate" again today. I'm worried about his stomach ulcers.
