I got a document to fax to the German Embassy, Visa section and the number is the special pay fax number. That's why I couldn't fax it at my office. I went to the Post Office in Hauptbahnhof. The one who served me was an old guy. I filled in the postfax form and gave him. He looked at it and said this is not a fax number. I told him, it's a special Swiss fax number from the German embassy. Also I tried to convince him that it's correct. He looked at me like i'm really stupid. I just asked very politely that he can try it for me. He said to my face "It's impossible to fax this in Switzerland and we don't do it here" and crushed the postfax paper in his hand, then threw into to trash. I was really pissed off but can do nothing about it.
I just went to another counter, asked the lady there to fax it. She happily faxed it and it is sent just like normal though I have to pay more for that number. I wanted to go back to the old man's counter and tell him but his shift was already finished.
I don't know why a person working at the very big post office doesn't know about the pay fax number, but more surprised at the way he treated me. He could at least ask someone if he's not sure rather than held on to his ignorant knowledge. And that really makes my impression of Switzerland worse
