So I did.
"Excuse me, could I have a £5 note, please?"
"Sure! Here you go. Have a nice day."
"Thanks very much - you too!"
And I showed my note happily to the camera with an expression of delighted surprise on my face, for entertainment value.
I presume this is some TV experiment about whether people pay attention or not. I have no idea what for, though. I love Medialand sometimes. :o)
