I am sorry, but a lot of America would disagree. Their coffee may not be anything special, but IMO the lattes are fabulous.
I do not mean to come across snippy, but I would like to be politically correct for a moment, if I may.
Anger being provoked by seeing a Starbucks in WDW seems a trifle extreme, maybe I misunderstood your statement.
You do not have like it (and many do not) and I am sorry you lost your favorite coffee house

, but if Starbucks was the reason they went out of business, it would appear to me you sort of stand alone in your area of the country thinking they are not that great. They can only go out of business because people are going elsewhere. Starbuck's did not put them out of business, people not visiting them did.
I still wish they would put a Starbucks in, maybe in DTD. Of course, that would be a long trek in the morning for a $5 latte.
