I'm an SCA (Speciality Coffee Association) certified barista and have, as part of my work travels, drank speciality coffee all around the world in many different coffee shops. Most of it is terrible. It's not that I have the best palate or anything like that; it's that most of the places have undertrained staff behind the counter and serve under- or overextracted coffee all day! Most of it is either acidic or bitter to the point where you're losing all the qualities of the coffee beans and upsets my stomach. I've only found a handful of shops around the globe that genuinely care about the craft and will serve genuinely good coffee every time. (e.g. Prufrock in London, Tim Wendelboe in Oslo) The rest of the coffee shops are worse than useless, I'd rather go to a Starbucks or even McDonald's for my coffee than upset my stomach with that crap.
