So i'm in college right now in an all male dorm ( I know it sucks). But one of the favorite tactics of organizations on campus is to get the hottest girls to solicit stuff in our lobby. For example there's a group of girls selling carnations for valentines day to raise money for some club. I've tried to sarge before with no success. What kind of routine/ opener should I use?

Make it known that you know what there up to, manipulating horny guys to hawk shitty products or further some cause. Tell them there trickery won't work on you, but good try. Plow awhile, because they may be a bit hesitant, after all they knew where they were headed to and most likely have their bitch shields fully charged. If the same girls tend to come back to the lobby again and again, then make sure to be the first to leave the interaction while they still want more. It sounds like an awkward situation for a # close. Give them a flyer to a good party or tell them to meet you at the bar or coffeehouse.
