Multi-tasking is so serious that workers are taking their work into the washroom, with disturbing results. According to a recent survey, one-third of Brits admit they've made a "stall-call"—that is, a call from the toilet, not just the restroom—whether for business or pleasure. And one in twenty said they've taken their laptop with them when nature called. The survey also found a significant—and disgusting—number of people eat, drink and brush their teeth while answering nature's call.
