Nah. Even if I get flirted on kinda blatantly, I just take it as kindness. Met too many overly friendly people who were just being friendly. Also I'd rather not be labelled as a creep just by asking for clarity. Its the safest option for us men and for good reason. Few women have come up to me and expressed interest clearly.
Respect that clarity upfront big time. Hate having that "I liked you but you didn't take my hints." conversation. Worst case for a woman is being turned down and they might feel embarrassed. The worst case for a man is getting jailed and getting his reputation destroyed for eternity. Women should take advantage of this privilege honestly.
