Yeah, that's why needed GM's judgement can conversation skill roll used to distract Tani shinobi (I know I need roleplay it but if rolls are asked I need know what I am rolling). As it's sitting on fence between conversation and deception skills. Deception is sneaky stuff and meant to deceive people, but you can draw attention of crowd with good performance skill (dazzle them) but same can be done with conversation (which combines sense motive, diplomacy and gather info same skill now). So it's more means to draw them into fascinating conversation with him than mislead or deceive them as he would ask questions, interact and talk with them like he would do normally but more in intent to distract them away from the booth.
