Here I’ll link you to a great post by 3kalb. I hate cell phones in public places. It’s annoying, it’s rude, it’s ridiculous.
Do you not realize that the others around you are annoyed by hearing half of your conversation? Do you not care that you’re holding up the line? Do you not care that you’re broadcasting intimate details of grandpa’s prostate operation to everyone? Do you not care that you’re talking at 3x your normal volume level?
Of course not.
