The manager explained:

- Hey! Guy, if you're in the company, there are two things you need to learn and the second thing we noticed is the cleanliness of the company. Have you cleaned your feet on the carpet before entering this room?

The young man replied:

- Of course, sir.

- And a further problem, the most important thing that we require from the employee is the honesty. There is no any carpet here.
