In September, the Texas Alcoholic Beverage Commission conducted a series of undercover stings to see if local businesses were selling alcohol to minors.
Major Mark Menn, Supervisor of Enforcement for TABC Region 1, said 20 gas stations, convenience and liquor stores were tested and all of them complied with state law.
He said they use a teenager, usually around 16 or 17 years old, to walk into the store and try to make a purchase. The teens are not allowed to lie about their age, use a fake ID or wear extra make-up to make them appear older.
