You and Sanji had met in the restaurant when it was very early on, so you were both fairly little, and since then you had made your transition, so seeing him in public you had run up to him smiling. He didn't recognize you. "Look dude, I don't know who you are but screw off." You start reciting your conversations and interaction at the restaurant and then he blinked. "That was a little girl I was talking to, you're a man." He pointed out with a scoff.
