That makes sense, but many give a tip even though you will never see that person again. You could walk out and keep that money to spend on yourself or your loved ones (assuming you have any). However, there is a little voice inside me saying I must not leave without rewarding the server. It is a cultural thing to do with our sense of fairness.
