I was in the queue at my local Caffè Nero earlier today (which I fear I am addicted to) and I saw firsthand the wonderful effect the marketing bods have had on the, you'd think, simple process of buying a coffee.
An older fellow in front of me made the hesitant mistake of asking for a small black coffee and a cup of tea (ah, a coffee bar virgin I thought).
The barista, as we will now call the trained serving staff, let the black coffee request slide by and assumed the poor pup meant americano (double espresso topped up with water in Nero's case).
