Maybe it's this way in all such places. I don't know. Like you, I'm sure, I try to avoid them., But every so often, someone we care about has a "meeting" in one of these places and there you are, waiting. Such was the case this morning when a relative had a rather long meeting with a machine made of magnets. Anticipating that the magnets might be running a bit late, I brought along my computer, thinking I could work while waiting, hoping that if the meeting went on too long, I would be able to find a plug.
To my delight, I found a place to sit, a very comfy chair with a coffee table in front, a light on the table behind. Ah-ha! There had to be a plug. A three-pronger, no less. I turned on my machine and ...! Wireless with a welcome notice, allowing me in as a guest, without even registering or providing my name. A good strong 5-bar signal at that.
I got to work, opening, storing, deleting, writing...and then and then...just behind me, the gentle plucking of strings. A harpist had come in, set up, not ten feet from me, all so quietly that I hadn't even noticed until she filled the lobby with a celestial serenade, the lobby, that is, of Beth Israel Deaconess Medical Center in Boston.
