The Miami Heat may be even more grateful to have clinched the NBA Finals at American Airlines Arena than on the road after their expensive post-win celebration was considered "on the house". For the second straight year, the owner of Story Nightclub allowed the team to celebrate in his bar for no charge after the team's decisive Game 7 victory.

David Grutman, owner of the club in which the majority of the team partied after the win, said the players ordered 100 bottles of Dom Perignon and three 3-liter bottles of champagne. Grutman also owns the club LIV, where the team celebrated their 2012 championship victory.

The owner claims the club usually sells the standard size bottles of Dom Perignon for $850 each and the 3-liter bottles of Jeroboams for $5,000. "I'm not going to charge the Heat," Grutman said of the $100,000 value of comped alcohol.

However, he wasn't so generous of the opposition when the Heat failed to beat the Dallas Mavericks in 2011. Grutman charged Mavs owner Mark Cuban full price when he and his team partied after their NBA championship victory in Miami.

The Mavs partied at LIV, which ran Cuban a total of $90,000 for a 15-liter bottle of Armand de Brignac champagne. The flashy owner reportedly left a 22 percent tip.

"We were in the back because his credit card was denied," Grutman recalled. "So he called up the people at the Centurion Card and said, 'This is Mark Cuban. We just won the championship. Can I please spend some money?'"

Grutman added that the billionaire's purchase was eventually authorized.
