Well, if the single experience point isn't enough, you have lots of clear fictional routes that can help you put pressure on the situation, right?
I mean, "Hey, give me your bathtub," is not really a very strong bargaining position, but "Hey, I've got your motorcycle, so give me your bathtub or I push it off the side of this parking structure," is a lot more convincing, crunch concerns aside. Seduce/manipulate isn't hamstrung, but it isn't fun or convincing when you don't accompany it with good fictional context.
