I loved my travel agent. But then I kept finding cheaper flights online without his help. I never minded hailing cabs. Until they were “lyfted” out of my life. When I got a smartphone — a portal into the world that ensures my day is never interrupted by inconveniences — I threw my Blackberry into the trash. The inevitability of waiting has been washed away by a tidal wave of digitization. I’m no longer the customer I used to be. My expectations are higher — and my patience lower — than ever.
