So, in short, the US Embassy in Austria made an agreement with McDonald's Austria to have their employees trained to contact the Embassy if an American needs help.
Personally, I think it's strange and kind of silly...and a really good idea. A lot of tourists or travellers can't reach their country's consulates or embassies when they need to, so making connections through institutions that are well known as part of that country could actually make things easier.
What do you think, NSG?
