The smallest functional window without obvious purpose

There is a long hall (15 meters) at the uni with a glass roof (3 to 4 meters high) and automatic ventilation. In the middle of this hall is this small window without obvious purpose. It doesn't provide much light, it doesn't provide much air either (to the size of this hall). The only reason I can think of is to put people with claustrophobia at ease.

Parking machine interface steps in weird order

Do you remember the worse parking machine ever? This one is not so complicated. But the question is why change the order of steps? And why inserting coins is not a step? And why we have to kneel to operate it (is it meant for children who drive cars)?

Taps 29: more towel dispensers than sinks and horribly aligned

This one is from "45 Photos That Will Annoy You More Than They Should".

At first I thought this is photoshoped. If true they have done a truly amazing job with all the shades. So I guess it's not fake.

Why five dispensers?
We can argue that is never too much. If every sink is used by two people at the same time it makes six possible users. So five dispensers are not enough. Maybe people haven't dried their hands and the owner of this restroom just got annoyed and put five as a reminder to dry hands? It's certainly eye-catching. Or maybe is to make sure that they don't run out of towels? If these wouldn't be automatic, I'd even say to make sure at least one of the towels is ready (so users don't have to roll them out with wet hands).

Why not aligned?
People are of different heights! A child needs to be able to reach for the towel :). Maybe to kill the monotony of sinks. Or ... to have people wonder?

Total success!

Taps 28: Tap to short so hads touch the sink

This one is from "45 Photos That Will Annoy You More Than They Should".

How many times have you encountered such design? I understand that making the taps shorter reduces the overall cost and the end user pays less as a result. OK if it's installed in private homes. But what does such choice tell us about the restaurants' owners?

The light switch not in sync

This one is from "45 Photos That Will Annoy You More Than They Should". I'd say 'no way' but I have seen this so many times. WHY?!? This is not helping us to make mental maps of the world at all. This is probably just some electrician playing a trick.
