Gratuitous

"This is weird," said Hank.

Chuck leaned over. "What is?"

"The receipt. See, it says, 'Gratuity.'"

Chuck laughed. "That just means the tip, dude. How the hell did you ever pass your SATs?"

"No, I know that. But the blank is already filled in. Look." Hank pointed.

"'Gratuity: Nudity.' Hunh."

"Oopsies!" giggled the buxom waitress. She clutched at her fallen blouse. Perky pink flesh jiggled everywhere Chuck and Hank looked. "Silly me! I forgot to button my shirt! Or wear a bra!"

They watched her wiggle away. "We need to leave," Chuck said quietly.

"Dude, what? Why!?"

"Mine says 'Violence.'"
