Butler just buggy all over the behavior is weird and butler doesn't really add any usefulness beyond extra gameplay value through interactions, anything butler can do you will mostly be able to do as quick or faster. By time you ring bell to butler receive instructions and execute them you could done it yourself, butler just a waste of time for anything other than joy of ordering him or her around.
Personally i wish you could assign a meal plan, example: Cross on/off Breakfast, Lunch, Dinner and (dessert?) and the meal sizes, then he could automatically do those task at fixed time. Whole ringing bell for almost everything other than change orders or reprimand or praise feels like a time waste, that doesn't offer anything valuable to having a butler other than Aesthetic and ordering one around(feeling).
P.S remember one time where butler just make a dozen dishes i never instructed butler to, then butler would only clean them up once they got spoiled. Was literally dishes everywhere there was a surface nearby, the dump AI doesn't even put dishes they make away in fridge just stands around getting spoiled.
