Nice and simply has worked loads times basically when you approach just use normal material but deep down you know you only have say 5 mins as you have told your friend to come and get you. So make sure do just enough to get her interested.

Then your friend comes in really abrupt eg,

hey man, whats up we are so late sarah keeps ringing me we gotta go....

U- oh i was just taking to xxxxx i havent managed to get her to buy me a drink yet lol

MATE says got to go, give xxxx your phone and get her to put her number in.

or words to that effect. If she has been talking to u for 5 mins odds on she will as its not U who is asking its your friend. U are also demonstrating higher value as u are late for meeting other girls! give it a try. If you dont want to move on after five mins, develop a code word to buy you more time. Gud luck!
