She always said that people are not aware of the microorganisms that live in the mouth and the disease they can carry/communicate. The mouth is arguably the second dirtiest place on your body (the first being your other orifice) and anything exiting either end would thus be full of contaminate. However, she always laughed at the idea of how people were grossed out by urine - which is by definition - sterile. Saliva is obviously much less innocuous. People get grossed out by pee getting on them, but have no problem kissing a stranger, so long that they are good-looking.

Thus, long story short - my mother would have said in the waste basket, hands down.

Then when you fill the sink to wash something those microbes could mix with the clean water. As for the bathroom sink now that is different, anything goes there because you don't clean dishes in it.
