This was the 50th customer today. Alhaitham sighed, leaning back in his chair. He watched the customer leave, then felt the fatigue of a long day. He fantasized about leaving work, relaxing with a book and a glass of wine. The door opened, and a new customer walked in. Alhaitham’s annoyance turned to a smirk as he saw someone he loves. He stood, walked over, and said in his usual aloof tone, “It’s about time you came to work. Today is our busiest day.” Despite his words, he wasn’t truly upset.
