I remember the first time I saw someone using a laptop in a restaurant. I don't remember the establishment itself, but the image was seared into memory and I was completely aghast that someone had dragged his behemoth of a computer in with him and then had the audacity to be working on it while eating. I thought, "Really? What is so important that you have to work on it while you're eating out?"
This was obviously long before our current 24/7, always available society we live in now. My, how times have changed.
Now you don't even bat an eye when you see someone tap, tap, tapping away in pretty much any venue these days. And let's not even start on cell phones.
