I work on a floor with approximately 120 people sharing one set of bathrooms (one men's and one women's with approx 6 stalls each). There are a couple of people on the floor who feel absolutely no compunction about bringing their cell phones into the bathroom with them while loudly talking to unknown third parties.
Today, we reached a new low in social etiquette when someone walked in and proceeded to change the call to speakerphone while doing their business. I sat in the next stall with absolutely no clue how to deal with the situation.
I'd like to be able to use the toilets in peace and know that my potentially embarrassing sounds will stay as private as possible. How do I address this? I don't know who all the people are who do this but phone calls in the bathroom definitely happen on a regular basis.
