The ritzy casino restrooms all have them now. You stick your hand under the tap and the water comes gushing out. 2 problems I have encountered are the water temperature and quantity. At the Aria, the water is so damn hot I defy anyone to keep their hands under there for more than 3 seconds without risking 3rd degree burns.
The other problem is the short length of a burst before you have to remove and reinsert your hands to reactivate the sensor. The Wynn takes the prize here with a record of 12 insertions necessary to complete humming "Happy Birthday" twice.
