Just spotted this:
US citizens who need help in Austria can now head to their nearest branch of McDonald's, because of an agreement signed by the fast-food giant.
The embassy says any American "in distress" or whose passport has been lost or stolen can get assistance from one Austria's 194 McDonald's joints.
Restaurant staff have been given the task of helping US citizens get in touch with the US embassy.
A 24-hour hotline to the embassy is part of the arrangement.

So it is official, McDonald's is a representative of the US government.
P.S., not sure what category this should have been. There is no category "Passports, Visas and other Travel Documents".
