1. You have to be old enough (read legal age) to be drinking alcohol. Remember it's not a College Fresher's Party and the legal age to drink in this part of the world is 25 years. There's a reason why legal age to vote is 18 and legal age to marry is 21. Government wants you to take these decisions when you are sober!
2. Respect girls. Respect guys. Basically respect everyone. If you don't like anyone please do not tell them on their face. You might want to bitch about them later once you reach home.
3. You should not be giving false information about your relationship status. This event is only for singles. If you are not single and still attend the event aliens will come and abduct you as they are looking for dishonest people to perform a few experiments on.
4. The responsibility of sharing your contact details with someone and interaction of any sort is purely your choice. You are free citizen of a free country. And of-course smart enough to exercise caution. We do not have a way to do extensive background checks on people who attend our events. We are simpletons. We are not NYPD.
