GAINESVILLE- The city of Gainesville is about to increase the consequences for nightspots that are penalized for underage drinking.

As a new school year gets underway, the three year old, underage drinking ordinance is closing the doors to some places to underage patrons.

The economic threat of losing business of that group is enough to get many establishments to tighten up their act.

Gainesville Police Officer, Joseph Crews says, " If we can prevent it before it happens, it's just safer and it keeps people from getting out of hand."

Crews is referring to the efforts to enforce underage drinking laws at bars and clubs. 

After a set amount of warnings, violators aren't allowed to admit anyone under 21 after 9pm.
