Hello Pool Boy

I'm the pool boy. I leave my card in the windshields of the vehicles parked outside the supermarket. I've just checked that it works for me. Specially at a certain time of the day. 'I clean your pool. Easy going, good hearted, always horny. English spoken.' They do understand. They do call me. They open the door and play. They are clever. I clean their pool. Until they tell me to stop.
