Isaac waited until after practise, after a long shower, and a few drinks at the pub before showing up at Quality Quidditch Supplies with his broom in hand. He had been being sarcastic when he asked for the late night appointment, his double words going right over Tracey Davis's head. He would accept the appointment, have his broom serviced and go about his way. In the end he was losing nothing except a few hours of time.
Flooing into the shop to avoid the curfew, Isaac cleared his throat to announce himself and smiled at the dark haired former Slytherin. He had been a few years above her at school so he wasn't too familiar with her but he knew her name and knew she was one of the best at her job.
The drinks he had indulged in made him a little less reserved and a little more cocky. "Hello, Miss Davis." He greeted her with a smirk. "I appreciate your willingness to stay open late to accommodate my schedule." He lifted the broom off of his shoulder and held it out to her. It was one of the newest and fastest models, in excellent condition. He took care of it but used it regularly, it could always use small adjustments.
