I might be generalising but in some countries (UK) it's common to not rinse soap/washing up liquid off dishes after washing them by hand. Being hypochondriac I was always curious about health aspects of this and feared something similar to what's described in the article.

I’m surprised that people don’t taste that in the food/drink they consume off their soapy dishes. It’s a distinct unpleasant taste that I tend to over rinse somewhat just to avoid, especially with cups/mugs where transfer is maximized.

Though rinse aid is for mechanical dishwashers only.
