I'd still put money that if you go into most of these shops and ask for £10's worth of Bitcoin they'll be all bitwhat?

I hope they actually do some advertising for this, because otherwise I can't see it being very successful, but I'm glad it's there. Hope I'm proved wrong.
I assume if this uses PayPoint then all you'll do is go in, wave the piece of paper at them and say "I'd like to make a payment" or something similar, they scan it, etc.. Without Bitcoin even having to be mentioned at all.
