Nah, you can easily get free service in exchange for rides to the dope house. Keep the ones you've met in your contacts list and whenever you're in the mood to get your carrot waxed just start sending out texts that simply read "hey" and it's almost guaranteed at least one of them will be in withdrawal just because she doesn't have a ride, and she will be more than happy to swallow your load free of charge in exchange for that ride. You don't even have to wait on her either, you just drop her off. She'll be in there a few hours getting high, when she's ready to leave she'll blow another guy there in exchange for a ride home.
