Hey Jez, that was brilliant!
When I first started to check the net I had to use public access computers , and this experience would have been my worst nightmare. Even now, I suspect it may throw me somehat if I wer confronted . May I have your courage and quick thinking - please?.
It goes to show that people do notice what is on our screens in a public terminal.
BTW - S of J, the responses were exactly the same as I have had many times at home in family discussions,
