In an interview with the Associated Press, Cuban said that he matches NBA fines with charitable donations of equal amounts.[55] In a nationally publicized incident, he criticized the league's manager of officials, Ed T. Rush, saying that he "wouldn't be able to manage a Dairy Queen". Dairy Queen management took offense to Cuban's comments and invited him to manage a Dairy Queen restaurant for a day. Cuban accepted the company's invitation and worked for a day at a Dairy Queen in Coppell, Texas, where fans lined up in the street to get a Blizzard from the owner of the Mavericks.
