M: Do you have any idea where Samuel is now? It’s already 10: 30. This is the third time this week he’s not on time.  Didn’t I make it clear that all waiters and waitresses must be at work by 10, an hour before the dining room opens?
W: You did, Chris. I understand you’re upset now but Samuel works in the early mornings, too, mowing lawns until 9. I think that’s why he’s been late so many times.
