Food at Potlucks- Am I the only one?

I didn't have problems eating at potlucks until..............I followed a Physician friend of mine into the public restroom at a race track where we were tailgating. He walked out without washing his hands. I have also been at his home, a very expensive one, where his cats walked all over the counter tops. He is known for his fantastic chili. I know him as someone whose cats walk on the counter and someone who doesn't wash his hands after going to the bathroom and also makes chili for others.

I no longer eat pot lucks.
