It might have been coincidence that she'd ended up outside the very same coffee shop that he was in - she looked pretty embarrassed at being caught there, judging by the way she was shifting her weight and playing with her hair - but that just highlighted his point, that it was all too easy to accidentally follow someone. Besides, Cappie wasn't a suspicious person, except where the Omega Chis were concerned and, even then, that was only because he knew their nefarious ways all too well. He was always willing to give most people the benefit of a doubt and tended to be a very chilled out person because of it. Judging by how uptight the girl was, Cappie thought he was probably onto the winning strategy.
Cappie laughed, shaking his head, and backed up so he could open the door fully. "Why don't you come inside?" he asked, nodding towards the shop's interior. "I hear this place does a great Cappie-cino." He grinned before adding, "That's a witty play on words, 'cause my name's Cappie."
