Dear Costa ‘Baristas’. Yes. There is a difference between Earl Grey (fragrant, bergamot, caffeine) and green tea (decaying pond scum, no caffeine). So when I politely ask you to give me the tea I’d paid for and not the one you arbitrarily decide to give me whilst you discuss photo bombing with your equally tango’d neighbour, please don’t snark back that ‘it’s all the same’. It’s not. It’s very far from not. And if you do it again, the mild mannered goth with the coffee stained manuscript in the corner may just have to barf on your counter top to prove it.
