One day, Sally went to work by the taxi. Unfortunately, when she arrived her office, she realized that she has left her bag in the taxi.

She became worried because in the bag was the material needing for the meeting to be held in an hour.

Half an hour late, she received a call from a man, told her that he was sending the bag to her in person. Wondering where the man knew her address and telephone number, Sally went downstairs. It was actually the driver which taxi she had taken. The driver told Sally that he had found his business card in the bag so that he could find Sally. Sally expressed her thank to the driver and hurried upstairs, heading for the meeting room.
