Can a stripper really show interest in you while workin a friday night..?

i mean, she was on me the whole night and i only paid for one lap dance, but i got like 20 by the end of the night, can she be interested or is it just a "hooking" method? and ive had the occasional, slip your willy out and they'll be "grindin" on it so the bouncers cant tell wats goin on....LOL...good times....
