Rolling the Dice

As my family and I went out to dinner at a Chinese Buffet tonight I realized that sometimes we really take some unnecessary risks. Who knows why we do it. Sometimes it's to save some money. Sometimes to save time, but sometimes we just don't think. Such as:

1. Eating Shelfish at a Buffet
2. Eating Sushi at a Buffet
3. Hiring a friend's friend to do some electrical work.
4. Agreeing to smell something right after someone whinces at the smelling the same thing.
5. Agreeing to fly with a friend who has a subscription to "Budget Flying".

Can you think of any....?
