Rant

Nothing bad happens in the post.

So, I have ordered something to Amazon locker for the first time.
It was already dark outside, but still just 19:20, so I went to pick up my parcel.
I got to the locker at around 20:30 (you see, the nearest locker isn't that close), while suddenly, I hear a car stop behind me, and I hear some German.
"POLIZEI", the car states.
Now, I don't speak German, but thankfully they spoke English.

"Where are you going?"
"To the Amazon box."
"Are you from [city]?"
"Yes."
"...OK..."
He sounded a bit confused/surprised, but it's just a 4km walk from the last bus stop at the other side of the border.

Well, I didn't wait after the OK, and just resumed walking towards the locker. They however stayed there, watching me.

"Well, this thing better be working.", I thought.
I typed in the code, doors opened, and the Police drove away.

I searched around if for some god knows what reason Austria has a curfew, nope.
Finally at last, while waiting for a bus back, I tried checking the locker on Amazon. For some reason, this is not stated on the order page. So, I go to my addresses, click to add a pick-up point, search for this locker, and would you look at that.
Open till 7pm.

But, like, why? It's just next to a parking lot, a few meters from the sidewalk. No locks, gate, anything.
