You are NTJ and I really don’t think it’s a big deal that you didn’t eat the meal. I don’t think anyone went around checking plates to see if everyone ate. At my wedding nobody came up and gave me a report on who cleaned their plate and who didn’t.
You are not the jerk but I would advise you to ask the morning of every transfer day what time you are leaving. Also - you know what day you are leaving so make sure your volleyball gear is packed that morning.
