Dairy Queen Inc., Minneapolis, Minn., is celebrating the unofficial end of summer by giving away one free small Ultimate Oreo Frappé (per customer) at participating Dairy Queen locations from 2 p.m. to 5 p.m. on Tuesday, September 6.

In a nod to baristas and specialty coffee servers, the DQ system will refer to its servers as DQ-ristas, during the Free Frappé Giveaway event.
