Gideon's Rule #3,672: When asked for directions, ALWAYS give directions, even if you have no clue where the place is. Make sure to make them complicated enough that you are pretty much assured of never seeing the person again, so that you don't have to worry about being held accountable for your false directions.
(of course, while good in theory, it IS a tad difficult for me to do in my community of less than 600 people)
