Administrator. Scenario 4 of 13. Honesty with money
The petty cash is short
You look after the office petty cash tin. At the end of the month you count it, and it is £20 short of what the records say. You are fairly sure you forgot to write down a taxi fare you paid out two weeks ago, but you have no receipt.
Nobody checks the tin except you.
The principle
With money, the amount matters less than the honesty. Report a difference as soon as you find it, say what you think happened, and never adjust records to make them fit.
