I was waiting for a box via mail, but it did not arrive in time. For this reason I went to post office and asked the guy in charge to learn if they will contact me somehow in case they cannot reach me. For this situation I used the following sentence:
Werden Sie zu mir kontaktieren wenn …?
His answer was:
Nicht ich, Deutsche Post wird …
Was my question bad as I used Sie in the sentence? Why did he think that I mean him by saying you. Of course, I meant the post. Or was he just making fun of me since he understood that I am not German?
