who can call for the clock in a tournament?

[Jackbet]

i thought it's only the players, right?
i played a tourney in my local casino tonight. the floorman and tournament director has a personal problem with me. so it happened twice this evening that he was standing next to my table and said "time, you have 60 seconds to make a decision" when i thought about what to do. is there a written rule somewhere? no player at the table asked for the clock.
