The future of airports? In Toronto, there’s practically zero traditional seating at your gate. Instead, the bean counters have replaced them with restaurant seating, each equipped with a touch screen menu with an 18 percent default tip. Handy for a quick, expensive bite or drink but not so nice for a long layover. So now there’s a long line of flyers camping along the terminal walls. We also saw this at the New Jersey airport. I hope San Diego doesn’t adopt this model.
