Nobody can convince me Alfred isn't a master at making sure everyone that eats dinner at the manor has a full meal of whatever food they can tolerate like? He helped raised Bruce and helped in raising some of the batkids, and I personally headcanon Bruce and several of the batkids are some version of neurodivergent or autistic, so this man will spend all day making a comprehensive list of who is attending dinner that night and who might just drop by unannounced after denying they'll come (looking at you, Jason) so that he can make food everyone likes and that won't disturb anyone's safe foods. It creates a lot of extra dishes, but he doesn't mind, because this gaggle of idiots is as much his family as it is Bruce's.
