For most, that is damn near impossible... I don't know of any independent coffee shops near me that take BTC. In fact, i don't know of any brick and mortar stores near me that do. To date, i have only been able to use BTC online.
It's early days yet. Plus, you'll only be aware of them if you go in. Some stores that accept them don't even state they do or explicitly advertise the fact. Let's see how many stores start accepting them in 2014 - I think you'll be surprised. It'll also be much easier to get smaller independent entrepreneurial shops to experiment with accepting them as opposed to big corporations. I'll probably buy a coffee with BTC the first place I see that accepts them just to try it out and encourage it's use.
