Some places you don't get the deposit if the can is crushed, because they need to be able to read the barcode. Which is insane, because crushed cans take up a fraction of the space of whole cans and only makes the recycling process more complex.

The self-service machines used in Germany to collect bottles and cans will do the crushing part for you (after reading the barcode)

Yeah, but collecting whole cans is inconvenient. My normal process is to crush it with my hands immediately after drinking it (top to bottom) so it doesn't take up so much room.
