Because WTF Luke Skywalker (spoilers for Last Jedi)
Carl took the stack of books from the lady and waited for her to hand him her library card. The lady was bent over, talking softly to something below Carl's reach. Carl waited.
"Can you fucking believe that shit?" Pam said, coming through the door from the circulation workroom behind the desk.
"What shit?" Carl said.
The woman shot up with her eyes wide. "Excuse me," she said high and loud.
"Excuse me, too. Fucking Luke Skywalker was gonna kill somebody for maybe being evil? The same Luke that got over his daddy issues and turned Vader to the light? That ain't the fucking Luke I remember," Pam said.
The woman said, "Young lady, you can't talk that way in front of Lucy."
Pam's face blanched and she leaned over the desk. She said, "Oh goodness, I'm so sorry little- what the fuck?"
The patron said, "I'm going to report you."
Carl said, "What's wrong?"
Pam leaned back and pointed to the door. "Get that fucking alligator out of here."
"I need the name of your supervisor," the woman said.
"I'ma get my gun and shoot that thing," Pam said and went back through the door.
The woman left the building, half dragging her pet alligator out the door, her stack of books on the circulation desk in front of a downtrodden Carl.
"I don't even like Star Wars," Carl said.
