Cash tips are always superior when tips are actually applicable. If its just on a POS system I never tip. If I am expected to tip before service is rendered I also won't tip, since how can I possibly know what to tip if I haven't received the service yet? For cash tips you can wait until service is rendered no matter whatever shitty POS service the restaurant owner contacted with, plus there is no risk of the restaurant owner pilfering from the tip jar if the money goes directly from your hand to your intended recipient, and taxes are de facto eliminated.
