Boo had promised to be there and to wake up earlier than usual. This was not a promise to be on time. Generally he was on time for work, but the rest of his life was much more casual. It was probably not the best way to go about life, flying by the seat of his pants like that, but he didn't much care for anyone else's opinion on that matter.
So, yes, maybe he was five... Okay, ten minutes late for his coffee date with Alice, but she hadn't left yet. That was a good sign. He would have gotten her a coffee, but oh well. He ordered himself an iced Americano before heading to her table and taking the empty seat. "You weren't worried were you?"
