Washing Hand

I work in an office on campus over the summer and I sit about ten feet away from the unisex bathroom in this office. There are 8 females and 7 males that share this bathroom. The funny things is I have come to find out that almost all the males that use this restroom do not wash there hands. How do I know this you ask...well it's simple but the time they are at my desk, their flush is finishing and they barely make it out the door with flushing, you would think people would take the time to flush a toilet let alone wash their hands. I have always been a washing hands kind of person and when I am using a public restroom, I always make sure that my hand sanitizer is ready to use before I even enter the bathroom. So I guess the point of this post is to wonder why some many people do not wash their hands the bathroom. If you are one of those people, please wash your hands! It keeps the restroom clean so germs do not spread. Thanks
