Starbucks is the worst coffee I've ever tasted. And that includes the time I was on a long road journey and stopped at a gas station at around two in the morning. I filled up a coffee cup and went to pay. The woman said "I won't charge you for the coffee it has been stewing for too long".

The one and only time I bought a coffee from Starbucks it tasted as though it had been brewed from old cigarette butts.
