A Washington business etiquette expert says people should learn to put down their smartphones while sitting on the toilet. Kate Zabriskie, owner of Business Training Works, said using the phone for any reason while sitting on the toilet runs counter to the cause of cleanliness. "If you're in the stall touching the buttons on the phone, that's not good," Zabriskie said. "Those just aren't clean hands. And even if they're immaculate hands ... it's just not an image that I would think most people would want to project."
However, Zabriskie said convincing people to put their phones down at any time is a tall order. "It's just almost become an appendage," she said.
