Maybe you should reply something like this “I will see if I can put it on my roster.” I seems like he wanted the confirmation that you are still there and easily agreed to dinner with him. If you put a bit resistance, maybe he will pursue you more, and you will have your steak dinner for sure. Just the thought.
