There was an innocent reason apparently, from the now top comment:

“This is Culver’s. They’re a burger fast food joint located throughout the Midwest and have things called “Scoopy Night” where a percentage of the proceeds go toward a specific cause. Schools, dance groups, etc can partake and the kids who attend that school/dance group/etc help take orders and deliver food to tables. Not quite as dystopian as OP has made it seem.”
