When I'm in the office I can't hear myself think, and anyone I'm on the phone with hears everyone around me. It loses us customers as they believe it wholly unprofessional. My employer has an open layout approach and no white noise along with no noise cancelling headsets, so all my customers and I hear is everyone around me. And some of these assholes take pride in being loud("you're telling me to change who I am!"). Luckily, I work from home or on the road the majority of the time, so I don't have to deal with it, but, ultimately, fuck open layouts. Give me offices, or at least tall cubes.
