I am still not convinced that I enjoy the gentle splashback as the stool hits the vastly over-generous lake of water in most public toilets :-/

Are you familiar with the paper napkins rolled up so tight they look like a peppermint, and when they get wet they unfurl? Maybe American toilets should have a jar of those things next to it on a shelf so you can quickly drop one in and go on with your business :)

For extra vintage meme, they should be shaped like sea shells.

Reality: there is a porcelain shelf with a permanent poop stain on it because no current is strong enough to remove the smear
