DFW AIRPORT (CBSDFW.COM) – A prominent minority-owned concessionaire at Dallas/Fort Worth International Airport may be forced to shut down some of his restaurants.

Thursday morning, airport board members voted to terminate leases for four restaurants owned by Gilbert Aranza.

But Aranza has asked a judge to approve a temporary restraining order that would keep the airport from shutting his businesses down right away.

The airport claims Aranza owes them about $300,000 in back rent.

Airport administrators claim Aranza’s businesses improperly deducted a tax on each liquor bottled opened from the gross receipts reported to the airport. Last June, the airport board found out that about a dozen concessions owed $750,000.   Records show since then, all of them have paid the airport back except for one: Aranza’s Star Concessions.

The gross receipts are used to determined how much concessions pay for rent.

CBS 11 News tried to contact Aranza, but he has yet to respond. A spokesman for Aranza said his company has not miscalculated its gross receipts and doesn’t owe the airport back rent.
