Key west is crazy strict about underage drinking. Trust me i know. They bring in a special police taskforce called the tobacco and alcohol police. Its not the bars that are strict, they are actually really lazy. Once place even scanned my ID on 3 different scanners that all said it was fake and they still let me in. The only thing that got me in trouble is having a drink out on the street. If the cops see you with a drink they will card you for sure. In florida they dont have minor consumption laws just minor in possesion so you can only get in trouble if they see a drink in you hand. If you do happen to get caught it is the worst time of your life. You will have court the next day at 8am and have the choice of a 200 some dollar fine or community service. Not many people pay the fine. I chose the community service and right after you choose they slap a orange vest with county jail written on it and put you on a bus. Then you get to go clean up the ditches for 8 hours. People yell and throw **** at you and it sucks. Honestly the bars were a blast and i sure got my fill of bews. I was wasted when they got me but the punishment sucked ***.
