Sad
In the mid-1980's I listed to James Martin speak at one of his seminars. It was a whole week long and I was glued to the edge of my chair for the entire time. He was a true visionary!
I still have his book "The Design of Real-Time Systems" on my bookshelf. His logic on queuing theory still works flawlessly.
Unfortunately, I think about it every time I'm waiting in a queue at the airport, post office or whatever. It tells me that I'm waiting in line because the airline, USPS, or whomever, actually *wants* it to be that way! Yes, folks, all the organizations could know, should know, and probably do know just how long you're waiting. It's 100% predictable.
