Some reasons, not all reasons.

Yeah, this seems like a case of "it's not my job to interperet my boss's incomprehensible behaviour on their behalf".

Our post office was closed for the entire day on Tuesday. No reasons given. Normally, about three to four people work there.

One customer scribbled something about Deutsche Post's disdain for its customers on the notice. But I'm afraid we are going to have to get used to this kind of thing.

It's like they're just scribbling random numbers.
