I saw an empty shop space the other day and my first thought was buy it and turn it into a simple cafe/diner. Heavily promote prices that are at least half the norm in my town but ONLY accept Bitcoin. Even if the shop sat empty for a year it would send a clear message. Also would be a cool place for bitcoiners for events and meetups.

That sounds amazing. The tricky part is to bootstrap it but it definitely makes sense to put a heavy discount when using bitcoin.
