There has been a lot of discussion in this thread and some how I still think it comes back to the airport experience which is generally poor and therefore easy to possibly upset or confuse staff as well as the passenger.
That said flew through Munich Terminal 2 yesterday - spaceous - lots of people actually working at the bag drop area - security passage painless friendly and quick (all security areas active) and free coffee around the departure dates. With many weary eyed passengers due to Octoberfest I must say everything was handled wonderfully and when it came to showing ID at the gate as well as earlier at baggage check in) it did not matter as no one was feeling harassed. LH did not check the boarding card on boarding.
