Honestly I am still struggling to remember the names of the coffee that I’m going to order in the coffee shop. I just couldn’t match the image of the coffee with the names. They don’t even call it small or big but instead short or tall. I just wonder when height ever applied to liquid. If you don’t find it strange, perhaps you can try walk into a restaurant or a bar and try this.
“Please give me a tall cup of water.”
“I like a beer, tall”
“I would like to have a cup of tea, short”
“I’ll have the orange juice, doppio”
Just watch closely on how waitress react as they take your orders. Perhaps only those who visited a coffee shop understand exactly what you are trying to say.
