Why shouldn't the whole thing be a package deal? The management needs to ensure every step from buying ingredients to putting it on a plate is done well, why is the act of delivering it to your table singled out? You vote with your feet by going back. Lots of other industries need face-to-face contact. It would not be a better world if we had to tip the dentist's receptionist, the office building's security guy, the plumber's apprentice who does comes back to finish the job... although it's still important that all of these behave well.
