Enthrallment Skill Used on PC's

[inflatus]

Should a GM allow a player to use the Enthrallment, Captivate, Persuade, Suggest or Sway Emotion skill on another player to make him do something that he is adamantly against? I can see these skills being used on NPC's but using on player characters might cause some issues. My opinion is that the GM should allow some roleplaying for the persuasion but it should never come to skill checks. The roleplaying should also be stopped if the conversation becomes personal out of game.

I wanted to know if any players or GM's have encountered this situation in their sessions and if so, what came about?
