Normally the airlines pick up the tab if you are caught not having the right paperwork at your destination to enter that country.
If you however enter the destination country and get deported from there, the local authorities contact the german consular service, who pays for deportation and is obliged to get it back from you once you are back in germany.
Hence german authorities take care that you have all the required papers when you leave the country.
