Police Chief Joe Treviño said Patrolman Garrett Davidson responded to the call, and officers set up surveillance at the theater.
They took a suspect into custody after searching him and finding marijuana and a pipe used for smoking the drug in his possession.
The suspect, Tyler Fink, was booked on a charge of delivery of marijuana, less than four ounces, in a drug-free zone, possession of marijuana and possession of drug paraphernalia.
The delivery charge would have been a Class A misdemeanor, but because the suspect was believed to have been selling the drug within 1,000 feet of a game room, the charge was enhanced to a state jail felony.
If convicted, he could be sentenced to up to two years in a state jail facility and fined $10,000.
The possession charge is a Class B misdemeanor, and the possession of paraphernalia charge is a Class C misdemeanor.
A conviction on the Class B charge could result in a $2,000 fine and 180 days in the county jail. A conviction on the lesser misdemeanor charge could result in a $500 fine.
The suspect was released the day after his arrest on bonds totaling $3,200.
