We have a similar thing here.
If you're early nothing is said. If you're late you get "Afternoon, shit the bed?".

In my previous job I was hauled up in front of my manager
for not acknowledging the personnel manager when she clocked me coming in 15 mins late. She wanted to know WHY I was late. There was no reason, I was just a bit late. She wasn't there the previous night when I finished a couple of hours past my finish time.
My manager had me make up a story about a broken alarm clock to accompany my apology to her, just to appease her need to know WHY?

WTF?
Stand at the door at 5.30 and when she leaves say "Half day?".
