And how clean do you think the "Public" toilet will be? How often will those be cleaned?
I've used the toilets in coach. The condition left by other passengers is a disgrace. I'd much rather have the toilet in the roomette and keep it clean myself, than to share the toilet with strangers that may not be respectful of others.
I'm not sure the other poster is saying the public toilets are clean, it's just that you don't spend the whole time time on the train sitting in the public toilets either.
I'm no germ freak, far from it. I like to camp, and when you do that you get dirty, share spoons, eat off less-than-clean plates/cup, and lots of other gross stuff. But sitting in a chair, directly next to a commode where males stand and pee........Hey I don't care if the train is dead-stopped. Men urinating from a standing position "spray". It's a simple fact, one can't not do it. And that spay hits the cloth covered chair, and dries, and there is stays. Yuck with a capital Y. Most men will not admit it........
Gross as it sounds, the manufacturer's of toilets and associated bathroom stuff actually do studies about this stuff, what materials clean the best, what materials are less likely to smell, etc., etc.,
If I'm ever stuck in a Viewliner Roomette, I don't care WHAT DIRECTION the train is going, you aren't gonna find my butt on the seat closest the commode, nor will I use it the entire trip.
Sure we can "advise" male travelers to sit while peeing, but that doesn't help the 10,000 people who were in the roomette B4 U.
