That protection does not apply to out-of-state IDs, but it doesn't mean selling alcohol to people from out of state is illegal.
Still, it's not uncommon for Texas companies and servers to refuse to sell alcohol to people who show out-of-state identification, said Carolyn Beck, a spokeswoman for the Texas Alcoholic Beverage Commission.
Some are just being cautious in order to avoid punishment from the TABC, but others may be misinterpreting the law, Beck said.
Commission agents are conducting sting operations at the State Fair of Texas in attempt to catch servers who may be selling beer to minors, regardless of what state they're from, Beck said.
"When the TABC observes an infraction, they could care less. They react pretty much immediately,” Black said.
Minors caught buying, drinking or being under the influence of alcohol in Texas can face a misdemeanor charge and a fine up to $500. Serving alcohol to a minor is also a misdemeanor in Texas and could cost the server up to $4,000 in fines and jail time.
