A feisty 70-year-old woman had to call a furnace repairman. After a quick inspection the man put some oil into the motor and handed her a $70 bill for labor.
"Labor charges!" she exclaimed. "It only took you five minutes."
The repairman explained that his company had a minimum one-hour charge on every house call.
"Well, I want my remaining 55 minutes of labor," the lady responded, and she handed him a rake. The repairman spent the next 55 minutes in her yard bagging leaves.
