Man, I hate Starbucks. Macons control it. I wouldn't spend my precious Bitcoins in some shitty Starbucks coffee. I don't even know how can anyone consider that filthy water coffee. Starbucks drink is everything but coffee, and even so it is a terribly awfull drink
even if you do not like it. but you know starbucks is a cafe with a pretty big names, with starbucks accept bitcoin, bitcoin certainly will be more respected and trusted, think about the effect dude 
The only good thing if Starbucks will accept Bitcoin is Bitcoin will be respected and trusted more yes, But if we are already a Bitcoin user what is the sense of going to Starbucks and pay Bitcoin when we can just pay flat money upfront. I used Bitcoin because i can transact wherever i am. But if Starbucks will implement deliveries then every morning i will avail from them using my Bitcoin.
