Shang Tsung hadn't meant to sound rash, or impatient. He genuinely had no clue how these things work as had never went to the Doctor on Outworld. He listened to everything, and caught on well enough. He found Sonya's thoroughness to be refreshing, because he himself was very thorough. He didn't directly reply to Sonya's comments, but he tried to listen as intently as possible to show interest. He wasn't quite sure about moving to London, but money wouldn't be an issue on that.
Everything else he made a mental note of, and wasn't surprised that he and Sonya had followed by most of these rules in Outworld... it seemed most everything was pretty logical.
