I happened to be in a fairly new building yesterday and needed to use the restroom.
I pushed the button on the wall and the door opened automatically.
I used the urinal and it flushed itself as I walked away.
I washed my hands in a sink with a motion sensing faucet.
To dry my hands, I had a choice of a motion sensing blower or a motion sensing paper towel dispenser.
Out of curiosity, I stuck my head into a stall and sure enough, there sat a motion sensing toilet.
So, tell me, why was there a manual toilet paper dispenser hanging on the wall?
Why are they able to automate the entire bathroom experience except for the dispensing of toilet paper?
