How is it that it's 2020 and you still think you have to shout into your cell phone? You do realize that your microphone is designed to pick up a normal volume of speech right? I find this insanity is most common among people who grew up in the pre-cellphone era, and are terrified that without wires their precious pearls of grocery store wisdom will be lost forever. How can you not understand that screaming into your phone does not boost the satellite signal? The person you are calling has a set speaker volume, but for those of us standing around you you sound like you are trying to communicate while skydiving, or maybe calling for help from the window of a burning building? Please stop. Your inside voice is annoying enough.
