There needs to be some way of verifying the Bitcoiner's success with the shops. I am unsure of the best way to do that.
best way to achieve this is to have the bitcoin 'teacher'/salesman do a video of him speaking with the manager of the shop about his thoughts on now accepting bitcoin and the manager thanking the bitcoin 'teacher'.
