Besides, he's here waiting to meet a contact, and while it's not as though he's afraid of his presence being found out, he doesn't need attention drawn to him.

By the second cigarette, he's growing impatient with his contact's absence, and that manifests in his annoyance with the man in the booth across from his own.

By the third cigarette he's abandoned all pretense of politeness and is leaning over and snapping, "Can you not possibly do that elsewhere?"
