Roll: thanks - so was the girl. Quite oblivious to everything but her machine. From when she came in, had her drink, to when she departed, she couldn't have spoken more than two sentences (short!) to her companions.
I suppose that had this been a camera, one of those screens that fold down would have been rather handy. Especially if focussing by touching the screen. Heresy! As it is, the iPad does have the advantage of not looking threatening, especially when I am connected to the darn thing with 'phones. If anything, I suppose that I come over as the vulnerable one.
