Does this woman ever wash her hands? God help her if she doesn’t. Anyway I have one piece of advice:
Eat at home folks.
Wash and cook your own food.
You can make a delicious cheese burger at home and make your own fresh french fries. The beat fast food anyday.
It's crazy. She could pass along hepatitis B, and all manner of things, from all kinds of surfaces. She must have some way of cleaning herself, and if she doesn't, I sure don't want her handling my food.
Eat at home folks.
Wash and cook your own food.
Always.
