Flirting Style

Well there is the I'm kind of helpless do you mind helping me, like what you might do at a store. The friendly banter due to a similar situation, let's say we're all stuck in the same classroom or line. The flirting you might do while working (I used to bartend) when a cute woman/man comes up. There are also terrible ways of flirting (I beleive), like thinking that by being a loud mouthed guy that makes fun of the establishement or people around you will get you noticed by the cute girl that just walked up to the bar. Stuff like that.
