Here's another one I just remembered. At the optometrist, they had me look into a machine which took digital pictures of my retinas. Later the doctor told me we could "develop" those pictures and she could look at them without dilating my eyes and we would have a nice record for future comparison - but this would cost extra. Or, she could dilate my eyes and peer in the old-fashioned way. I went with the modern more expensive way, and she said, "OK we'll develop the pictures" and with a click of her mouse, there they were. The "magic" of digital "development". Of course the work of having me sit in front of the machine had already been done by the technician. It cost me extra to save the doctor from basically redoing it the old way. (Not to mention they didn't have to send me home with disposable sunglasses.) Just another funny pricing model for you. Value to you is often priced higher even if it costs them less.
