I've found myself repeatedly needing to ask vendors for change in certain ways, and I realized I have no idea what words are used for this.
So far I've been getting away with this:
Vous avez de la monnaie ? (I hold out a €5 bill) Je voudrais deux deux et un un.
Of course I'm trying to say that I'd like two €2 coins and one €1 coin. People usually understand but it's not very smooth. In English that's exactly how you would say it though-- "Could I get two fives and a ten?" And then for coins we specify quarters, dimes, nickels, etc.
How is this done in French, with the euro?
