Along those thoughts....
Use your hand drying towel to open the public washroom door. I see too often inadequate or no hand washing after using the restrooms.
I feel cabins don't really extra cleaning. Disease is more likely spread on handrails and door knobs.
I do use a blacklight on the first time I enter my cabin or hotel room to see where I need to direct staff to do some "spot" cleaning on walls, carpets, or other surfaces.
