My friend is a Flair instructor and judge. He offered to teach a course at Caribe Island in exchange for his room and board. When we checked with the labour dept, we were told that it is illegal to do it behind the bar of an establishment. It would also be illegal to charge for a class. However, if you would like to volunteer to teach a class that was held outside of a bar, then you should be able to do it.
I would love to see some bartenders throwing rum bottles!!!!
