Hope that works out for you mate, a friend of mind attempted the same thing, he spent weeks going into his local Tesco to see a woman who was working on the tills. Eventually he plucked up the courage to buy her a bunch of flowers and ask her on a date, only to find out she's a lesbian with a girlfriend who likes to dress up as a man on the weekends.
I shlt thee nay.
Risk it for a biscuit!
