Wow, thx for the list...
Well, since Bitcoin is a worldwide payment solution (it's more than that, I know...), it'll find a lot of scenarios of use.
Personally, I enjoy McDonald's, Burger King and other major fast food chains, I just like it (as well as I like burgers from smaller restaurants ).
But the reality is, most people will buy at the cheapest place. Those who can offer such products today are large business.
There are simply no small markets (groceries) around me. The same can be said about drugstores.
Even the small business owners runs mostly franchises.
But that's the reality here where I'm living now. Where I used to live before, most of the business were local.
I might be wrong, but the best scenario for Bitcoin is a universal adoption and for a lot of time it'll work side by side with other payment solutions.
Gotta understand most people care about saving their money (or Bitcoins) and not too much about the ideology.
IMO, for business adoption, especially the small, the best reason for Bitcoin is tax evasion. Again, that's a truth where I live, it might be different somewhere else...
