asking this girl out - advice please
	
	
		Im 19 and male, theres a girl at my hairdressers who i think is pretty nice and i was obviously attracted to her. Now When i went for my haircut last week i was thinking about asking her out for a drink/movie/meal or something but didnt know how to go about asking her.
Now il probably be having my haircut again in like a month-2 months so that will be the only time il get the chance to but how do i go about it?
The hairdressers is full of women and shes sort of liike just helping out (ie training i think so takes calls, cleans up etc) so its not like i can say anything while she cuts my hair. Do i just chat with the girl who does my hair and see what she thinks about the girl?
Im not exactly the most upfront guy so i cant just go up to her and ask her out. and i dont want to be knocked back then will feel like a prat when i next go in. andi dont even know if she has noticed me or anything. Thinkshe is 17/18 if that makes any difference?
i had some other advice about ringing the hairdressers up and asking to speak to her and telling her who i am (ie the guy who got his hair cut on x date) andasking if she wants to do something. But i just dont think i can do that. 
this might sound weird/selfish but im scared (scared might be a harsh word, maybe nervous) that things go wrong and when i have to go to the hairdressers again it will be very awkward. 
cheers any help welcome ta :)
