Look, the article even says so:
Patrons were invited to make good on unpaid fines by donating canned and packaged foods for the local soup kitchen or by entering a dance competition, “Dance Dance Revolution.”
To sweeten the pot, during most of the day the library served coffee, bagels, pastries and ice cream, donated by area businesses.
By midafternoon, the cans and packages were piling up on a table inside library director Michelle Sampson’s office while circulation assistant Katie Spofford was setting up the video dance game on a PlayStation in a carpeted room upstairs.
I'd still probably lose, though. When it comes to DDR, I'm strictly a White Guy Beta.
