connie, you wouldn't believe it but that's exactly the sign that we needed to post in the bathroom of our tour bus. I had the unpleasant task of cleaning the darn thing and you wouldn't believe how many foot prints I had to wipe off the seat after some groups finished their trips. GEEZ Hubby always worried that if he had to slam on the brakes while they were in there they would fly off the seat and sue us. LOL
Hugs, Mari
