If you're going out alone, here are some pointers
[*] Arrive EARLY, bullshit with the security, get to know them briefly, talk about the club and good club nights and the city and being security and the weather, the girls, etc.
[*] Get to know the bartender. Tip them $5 or $10 and tell them you're going to be coming to them for water all night but you want it to look like a drink so you can act drunk and be taken advantage of by the ladies. (meaning add garnish/straws)
[*] Meet the promoters, same talk as security. Tell them you're a regular clubber and you scope out clubs for you and your friends to come to and you'd love to be on the list - get their phone number.
[*] Here's a ZINGER: many times the HGVs will be there early because they are very good friends with the promoters. MEET THEM. They are the super-hotties. Go introduce yourself, cheers them with your water, compliment their outfits and roll off and talk to another security guard about how cute those chicks are.
[*] The club will start filling up - game on. You already know everyone there is to know in the venue. You're the man, this is your party. BRING THE PARTY to everyone. Give value. Work the room doing short-set method (cheers, high fives, 'Hey!/smile', etc: open high energy/eject)
[*] Now go back around re-open making brief statements and having brief interactions. The club is yours, you are lording, you have your choice of the ladies of the realm. Enjoy.
As you go back week after week you will meet other regular clubbers like yourself. They will be your new 'social circle' in the club - just a group of ppl u regularly bullshit with when you go out. After one week you will no longer be 'flying solo' because the staff/security are your friends - goof off with them, have fun. After a couple weeks the regulars in the club are your friends too.
Congratulations, you've learned the art of lording a nightclub.
