So may two lads and I were just about two leave the gym when one of my lads saw this rather fine girl. He kept staring and staring at her doing flips and stuff and they even exchanged I contact a couple times. I suggested he go up and talk to her and of course like I would have been, he was scared. So he ended up having my other homie ask the girl for the number. The dialogue went like so:

Homie: "hey my friend was wondering if you could get your number"

Girl: says nothing, gives a weird look and blows him off.

What was wrong with this approach? When you do approach someone completely random in the middle of the day NOT in a social event/gathering like club/party whatever, what do you say or how do open up a conversation? Bus IMO going straight to the number seems overly awkward and doomed to fail. thanks
