This type is pretty good, but for food service workers, hospitals, and retirement homes, I’d prefer the hands-free ones with wide nozzles and oscillating sprayheads. Norovirus is a stupidly contagious GI bug, and for healthcare and food service, I want as little fecal-oral contamination as possible. Hand washing is great, but some people are terrible handwashers, and minimizing the potential vectors as much as possible is always appreciated.
Toilet paper itself is already pretty unsanitary. I wish all food service places had bidets for this reason alone.
Any bidet is better than no bidet. The hand ones are great. But the Japanese ones with zero hand contact minimizes the potential for fecal-oral contact even more, just in case someone doesn’t do a great job washing their hands in a hospital or food service setting.
Side note, it really irritates me when people take a shit, wet their hands, and leave. Wash your hands with soap and water. It takes 20 seconds.
If you don’t, you are now slinging potential shit water everywhere.
