Most Helpful Girl
When i've been approached in one instance, a guy asked my ethnicity and since he was of the same one then a conversation ensued. It was casual and not too confronting.
I would like to be told straight up simply that I caught their eye and they find me interesting and want to know my name. That way I have a chance to accept or decline (esp. since you don't know if I am single or not). If I give my name then that is a sign of some interest and we can continue a convo.
Otherwise a guy approaching with a compliment with something like my shoes, clothes, hair, smile etc. They can then ask name, age etc but not too creepy questions2
