According to our statistics New Year's Eve is the second biggest bar night of the year, only slightly behind Halloween.
Serving alcohol to a minor could result in a $2,000 fine, or depending on how egregious your violation is, the loss of your liquor license. If you think someone is underage do not let that person in or serve them. The risk is simply not worth the reward.
We also recommend electronically checking everyone's driver's license which proves due diligence (i.e. that you checked everyone's ID). Don't let a 19 year old with a fake ID ruin your business.
