Do you allow Charm to work on a player? Coercion, Deception, Negotiation all have tangible results. Being gregarious and susceptable to Charm sounds more like role-playing to me.
Absolutely, but the description of Nobody's Fool says it's possible. I usually work Chram checks to deal 2 strain per uncanceled Success to players who ignore the desires of whoever they've been Charmed by, but in some situations I might also lift the rules for fear. For instance, say you're negotiating with a Black Sun crime lord, and a Twi'lek dancer working for him keeps telling you to just agree to the deal so you and she can get some private time. Assuming she's serious, the player might get Charmed and thus either take strain or perhaps suffer a Setback die or other penalties to checks with the crime lord.
