At the mall, there are the standard options which includes flushing sounds. Yes, it really makes the sound of a flush without flushing. This is apparently to help drown out naturally occurring bathroom noises.
The office had similar features to the Mall. Again, as a public restroom you want the ability to maintain your dignity in the bathroom.
Maybe on my next visit, I will be brave enough to some of the features. My concern is where the water is coming from. And then the drying....I just don't know.
