They had these out in shopping centres in Australia, but they didn't last very long. It's a hard sell, I think you needed to get down to underwear in the thing?
Dug out an article, didn't read, but the picture is the device I recall.
Glad I wasn't making that up Hah! I think the main mistake they made was throwing these in the middle of shopping centres (similar placement to vending machines). If they had managed to get them integrated into a store, and made users feel safe, it might have been more successful.
Yes, you had to be in nothing but underwear, which was funny because when my dad tried it, we were in the middle of a massive convention centre.
