Dont let me started please, I got about 200 numbers at clubs in the last 3 months, so many that I dont even remember the faces of most of them.
I realize clubs are more of a "heat of the moment situation"yet the % is still low.
Do you know how many sex sessions I got out of it? less than 10!
Yeah exactly, I can tell for sure that getting a number at the club its pointless unlike you manage to speak with her at least 30 minutes and get the making out achievement on the sofas for many minutes.
However the hardest part is getting a date after the first meeting at the club, usually after the first date althought not easy is still less difficult than get a further contact from the club night.
As many said already, its not uncommon for girl to give numbers to get rid of guys or simply because they wanna avoid drama.
I can tell you for sure that a benchmark to know if that number is leading anywhere is the time you spent with the girl and the entusiasm she shown while giving it to you.
Those providing unrequested info are usually a safer bet althought not a sure one, girls who give you their number and their family name without being asked are usually game on while those who give you the number without asking for getting their phones ringed are simply showing open uninterest.
Now let me share a trick with you, if you really wanna gauge her interest in you while exchanging phone number just say that you wanna take a picture with her, those who refuse it for whatever excuse or hide their faces are most likely to give you nothing, while those accepting and posing with a open body language are the ones who are safer to bet in.
Take the picture if allowed and check the position of each toward the other, your gut will tell you better than I do
