He nodded absently to the guards as he passed by, like an officer would to his men, the kind of thing one would do to foster the illusion that they cared than anything else. What they didn't see was him quickly scanning their uniforms, making sure the general details were right, despite them not having any officers on the gate at the moment. No doubt the officers had already left for lunch. Once he was out of sight from the gate, his uniform would slowly begin to change, a subtle thing that wouldn't be noticeable unless someone was following him for several hundred yards and several streets, as he took turns and shortcuts while still maintaining the decor of his rank. However, by the time he got back to the inn where he had a room, he was in more normal clothing.
