It takes a lot of guts to go up to a random stranger and start hitting on them. While there's a chance that things will go smoothly, there's a better chance that the interaction will result in confusion, revulsion or a can of mace.
I don't have the stats on that, but I think it would hold up in court.
Being attractive seems to help, and while it's doubtful that Andrea from whatever would have any problem picking up guys, she decided to make things a little more challenging by hitting on women. By the end, she manages to get more phone numbers than I currently have in my phone.
It would appear that if a hot girl asks another girl to go on the date, the appropriate response isn't an immediate refusal, but: "Why not?" That's right guys -- all you have to do is be a good looking girl and women will flock to you in droves.
Do with that what you will.
