This is simply not true. I haven’t eaten meat in years but back when I did I would’ve gladly bought some NY hot dog cart water at the grocery store to add to my hot dog water when making it. It objectively makes them taste better versus using fresh water.

I would contend that soiled toilet water is the opposite. Like a dirty unkempt toilet that doesn’t necessarily have a full poop in it but maybe some residual shit pieces or those streak marks that happen sometimes. A drop of that on anything and I’m like well I guess I don’t need this that badly
