A restaurant's staff overreacted when they called the police when George W. Bush's daughters were suspected of violating drinking laws, the owners say.
The emergency call led to Jenna and Barbara Bush being charged.
They are accused of violating toughened underage drinking laws signed in 1997 by their father when he was governor.
"We believe that we made a mistake in calling the police in this matter and using 911 was a mistake. You don't use 911 except for in emergencies," Chuy's restaurant co-owner John Zapp said.
He said the restaurant should have just refused to serve the alcohol.
Co-owner Mike Young said that the manager who called police will remain employed with the company.
"A packed restaurant with high-profile celebrities there puts a lot of pressure on your management team," Mr Young said.
Captain David Ball of the Texas Alcoholic Beverage Commission said restaurant employees usually don't call police to report a suspected alcohol violation by a minor - and rarely use the emergency number.
"That's the decision they have to make," he said. "For your normal misrepresentation of age, it would be very unusual."
Police have charged Barbara Bush with being in possession of alcohol, and Jenna for allegedly attempting to buy alcohol with false identification. A 20-year-old friend of the women has also been charged.
