People Who Make Noise Inthe Bathroom

I hate whenever I use a bathroom stall in public or at work and there is someone in the stall making a lot of noise. Its akward enough using a restroom in public but do you have to sigh, grunt, and breathe loudly as if it was the most strenuous activity in the world? I hate the fact that I can identify every time you pass something. Shut your mouth, for god’s sake!
