Companies want feedback on all sorts of things, including the cleanliness of their restrooms. I don’t know who is going to call a phone number and report an unclean restroom. There are even tablets mounted on the wall where you can tap a happy face or a sad face to indicate your opinion about the experience. That would be interesting data to see.
I was in a fast food restaurant and the light was out in the restroom. It meant that I had to use the flashlight on my phone to see what I was doing. I reported that to the sandwich artist out front.
Would you ever considering adding an easy survey to your home restroom, so visitors can let you know how satisfied they were with the experience?
