I'm an expert on the matter. That's what I've always done because of the same reasons and friends hate going out with me because I wander off almost instantly.
I was retarded and didn't know that people never went out alone. It's made me pretty hard pretty fast. You face a number of unique challenges. One that wouldn't effect people in groups is chodie staff cockblocking and "protecting" the girls. Chodes in general hate a guy who will just walk up to the people they wouldn't have the guts to. "Hey! He can't do that! He's all alone, he should chode out at the bar just like I would! Protect to woman!".
There was a spectacular case of this just last night where the whole staff went into a frenzy because I landed at a table of 2 pretty girls. Instantly staff started fuckin up my set. I ended up throwing $5 on the bar, walking out and writing the owner.
The upside is that you can come and go as you please, sit where you want you can't rely on anyone so you either push yourself, or chode out getting pissed off at guys like me.
Respect, do you tell the set that you're alone?, 'couse than you can't use a FTC
