Arm over your shoulder? What about those who start massaging your shoulders? Or even better, the ones who sidle up to you at the bar, strike up conversation, and begin tweaking your nipples or groping you? (In my experience, the latter fall into 2 groups: the ones trying to con you into lap dances who deliver practically nothing once you agree; and the ones -- often the younger twinkier types -- who enjoy flirting and foreplay. The latter are almost always good value in the booths.)
