I just saw an article that cited rule 116:
116. Etiquette Violations: Repeated etiquette violations will result in the imposition of penalties assessed by the Tournament Staff. Examples include, but are not limited to, unnecessarily touching other participants’ cards or chips, body, or clothing, delay of the game, repeatedly acting out of turn, betting out of reach of the dealer, or excessive chatter. Excessive chatter includes, but is not limited to, talking or conversation that causes a disruption of participants who are in a hand.
The tournament floors/directors should carry the rules with them and know them well enough to show players which rule(s) was violated.
