I hate that they don't rinse here as well. I always rinse my dishes. My husbands friends and family never rinse and it makes me sick. Plus i watch my mother in law wash her dishes in a nasty, soapy, bucket with out rinsing, half the time she doesn't even actually wash the silverware unless there is actually food on it. I have also notice she uses the same old sponge for way too long, weeks! I never use a sponge more than once without sterilizing it. When I am at her house i try not to drink or eat anything. It drives me crazy. I am very aware of germs and bacteria and keep a very clean house. I disinfect everything often. I always bleach my sink and the little plastic dish bowel thing my husband thinks you need to wash dishes. I wont even let my husband clean a single dish because he wont rinse it. Plus , I always put a teaspoon of bleach in my dish water when washing dishes to kill germs and bacteria (yes, it is safe). And the funny part is they think that will kill you...ha!
I am not obsessed, but ever since working in the medical field I am very aware. I just like things to be clean.
