Answers to questions no one asked

In my recent trip I noticed that public bathrooms everywhere have installed those toilets that flush automatically. They flush early and often, but then when you finish your business they don't flush and you have to push the button to flush them again.

They're always paired with sinks that sprinkle tiny amounts of water if you put your hand under the faucet. As a result you can't get warm water unless you wave your hands perfectly in the cold water stream, for far longer than anyone has patience to do. Maybe this saves enough water to make up for the extra water needed to flush the toilets repeatedly.

Do these designers never actually use bathrooms? These plumbing items are an answer to a question no one asked.
