get dressed in the middle of the night and find a public toilet??? i don't think so !!, something seriousley wrong, if human beings cannot wander off to the loo dressed in night attire, i did last year, no one blinks an eye lid !! don't be such a prude, have a sence of adventure. a curtious "good evening" works wonders , well it did for me, but then i am a pretty blonde, with a smile to die for, so the conductor said!!
I would say that depends on what you wear at night. I am perpetually overheating in my bedroom at home at 69°, so I sleep with just underpants. I sincerely doubt people would have no problem with me walking around in my briefs. Now, if I wore PJs, it would be a different story, obviously.
I know some do favor this floorplan, but I could almost certainly say the entire toilet/sink combo is NEVER cleaned or sanitized between riders. Now, I know the same is likely for the community bathrooms on the Superliners, but at least those facilities ARE NOT WITHIN INCHES OF WHERE I WILL SLEEP.
You know, somewhere, sometime, people started becoming germ-o-phobic. What the heck do you consider "sanitized"? Spraying it with Lysol kills 99.9% of germs. However, within hours of its use that .1% of the strongest germs present are back and reproducing and probably filling the room to the point where they become concerned with carrying capacity.
As for the germs being within inches of where I sleep... well, my feet are on the end of the bed near the toilet. I'm sure you've never stepped in crap before. Most people have, its one of the joys of pet ownership- the finding of a present with your foot in the middle of the night. So who cares?
And as for the physical surface you sleep on, they don't need to sanitize it. They call the process of cleaning it "changing the sheets". Which they do after every run, trust me.
Everyday, in every way, we come in contact with millions, billions of germs. It is my experience that, outside of washing your hands sometimes, there is not much you can do to significantly affect your contracting illness from them.
So what you're getting down to isn't cleanliness, sanitation, or safety. Its simply your ew factor. And getting all ew over things is what we call childish.
