First Encounter With A P

The young man came again to Ajay and asked, ‘Which number you have selected sir?’
Ajay looked at him with a question mark. He understood something and told Ajay, ‘For one and a half hour 2500 Baht. You can enjoy fully. All are fully trained to give you full satisfaction. For every next half an hour additional 500 Baht you have to pay.’
Ajay looked at the watch. It is the time, when his daughter sits with him for her home work. He stood up from the chair and proceeded towards the glass door.
