Why don't they have waiters in waiting rooms?
The way we treat people we think can't help or hurt us - like housekeepers, waiters, and secretaries - tells more about our character than how we treat people we think are important. How we behave when we think no one is looking or when we don't think we will get caught more accurately portrays our character than what we say or do in service of our reputations.
Waiters will always pee in soup, people will always fall in love.
Waiters are like hookers, never around when you want them.
We must have been hunters and gatherers but some of us were just waiters and hopers.
