How would you answer this question?

Just got off of the phone with someone with over 30 years of HR experience in the world of convenience retailing (we use to call this segment convenience stores). We were swapping some ideas when she said one of the questions she always asks managers when they hire someone is: "Is this someone you would be willing to take home for dinner?" If the answer is "no," she wonders, why would that person be hired to take care of their customers?

I would like to change the question a little bit and ask instead: Would you be willing to have this person stay at your house over the weekend while you were out of town?
I wonder how many of us would rethink some of our hiring decisions then?
