I just unknowingly spent turns making some SHC drinks because my bartender died during the first one. I'm pretty sure Mafia used to warn me when this happened. I can't find anything about it in preferences, though. Am I misremembering things?
On the creation page you can fill in two tickboxes, one to use box servants, one to automatically make another. If you have the first ticked but not the second it'll warn.
