Spike, who is with me, reminded me before I went to the cafe, that I do this myself (sometimes) with my keys thereof. Not carrying them on full view for photo opportunities by everyone with a photo mobile phone, but on occasions when leaving them at my side on the pc desk or on the counter. So I am not faulting them for this action, and I do not expect them all to stop doing it. It looks to me like it has caught on big time, so all that remains is for the computer key-cutting programs to catch up. See, I have told you in advance before it happens.
