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?
