I don’t know about you, but I end up using Deutsch (well my broken and cringe-worthy Deutsch) the most at the supermarket – when I’m looking for something or at the cash register. When I first landed in Berlin, going to the supermarket was such a scary, anxiety inducing ordeal because of the Deutsch I’d be confronted with, from the products to the communication with staff. So when we did an exercise in class which required us to create sentences as supermarket customers and staff, I listened eagerly and greedily kept the chits of paper. Very useful!
