I'm a tiny bit of a germaphobe, it sort of snowballed when I started working in a doctors office. Germs and yuckies squick me out pretty bad.
At Costco, I was strolling around the meat section at about 1pm looking for some ground turkey, there were numerous sample ladies around giving out samples of hummus and other dips. While looking at the hummus that was in the cooler I look to my left and see one of the sample ladies stick TWO of her fingers into her mouth, nearly up to her knuckles - while wear gloves! - to lick off some of the dip on them.
I seriously went D: in her direction and gave her a look of utmost disgust and shock, she looked a little stunned someone had seen her and peeled off ONE glove (yes... ONE of them) and went digging for another. This alone led me to believe she had no intention of changing her gloves since she couldn't seem to find a NEW pair.
I brought it to the attention of one of the other sample ladies, expressing my concern that god knows how many times she's done that and NOT changed them, she's spreading spit all over the crackers and everything she is touching!
