As the interaction with the retainers tend to close the menu which required for me to reopen the menu of summoning bell which I usually do in my Inn, I would click on summoning the Aesthetician by mistake which would starts the whole mini cutscene and the character interface which would take a long in order to exit from.
In order to avoid the mistakes of summoning the Aesthetician, I believe a small confirmation message that is similar to when you about to discard an item would be a real help to avoid such mistakes.
