Three people were out for dinner and thier meal cost $10 each, they all gave the waitress a $10 note each which comes to $30. When the waitress took the $30 to the boss, he told her to return $5 to the three. On the way back, the waitress put $2 in her own pocket as she did not know how to split $5 between 3 people. She then gave the diners back $1 each.... Now because the diners got a $1 discount each off thier $10 meals that is a total of $27, plus $2 the waitress stole is $29. Where is the other dollar?
