No it is not. It is to you and your context. When it comes to plant-based milk, anything other than soja and almond is considered very exotic in France, most of people have never tried it. French people have coffee black or with cow milk. Lactose-free cow milk is part of everyday life and most of people don’t have milk in their coffee if they don’t want cow milk. As for latte, it is not a everyday drink but a treat and in many place people will not understand you are ordering a latté (litt: of milk) if you don’t even plan of having milk.
