I take my car to the dealer for service, and always wait for it. Over the years the waiting room has changed, gotten fancier and fancier. The last cycle boasts fancy leather chairs with arms for your computer; the previous cycle had just four seats against the wall for PC users. Of course, I'm not sure the chairs work so well for people using smartphones and iPads, but that's another story.
Anyhow, back in the day half the people waiting would be reading the newspaper, the other half zoned out watching CNN on the TV. Today there was one person reading the paper, me, and the rest were on their laptops or phones. The TV was going, but no one was watching.
The other change in 30 years has been from a mostly white clientele, through a mixed white and Latino clientele, to a Heinz 57 varieties from every continent.
