It's just like Coke: even if it's unhealthy, the brand convinces you to try it out. But we have to put away the taste and everything else: because Starbucks is VERY popular worldwide, accepting Bitcoin as a payment method would be a pretty important step for us. I'd like to buy food and drinks anonymously, with a few taps only. If you won't spend your money on Starbucks you'll spend it on something else one day and you'll regret it maybe even more. What matters is the advertisement Starbucks would make. If there will be ads placed around mentioning that "Bitcoin is accepted here", more people will come from around the world. We need a bigger community.
