I too had an iPad ordered on my account all of a sudden last week, to be delivered the same day to my home address - luckily was able to get it cancelled before it got that far.
Not much to add except I also encountered the same guy across the road from the cinema last night, who gave exactly the same spiel, asking for ?8. I gave him a quid and he immediately walked off without saying a word - sounds like I got off lightly!
