Robert Pattinson has urged up-and-coming stars not to complain about set conditions on film shoots - because he has witnessed crew members getting payback to diva demands.
The Twilight star insists stagehands and prop bosses have all the power on movie sets, not actors and directors - and he has learned to keep his mouth shut, even if he's unhappy.
He tells Britain's Esquire magazine, "This actress was doing a scene in the bath and she kept complaining about the temperature; how it was too hot or too cold. So everyone p**sed in it and put a bunch of bubble bath in afterwards, so you couldn't smell it!
"This stuff happens. That's why I avoid asking for anything. I don't want to get anyone's p**s on me."
