<human>: I know my question may seem absurd, but I saw something this evening that really made me think. My family went out to eat at a nice non-chain Italian Restaurant, with middle of the road pricing, that is a nice place to go for Father's Day. There was a family sitting next to us and they were having a great time, seemed to enjoy the server (which was also ours - she was great), liked their meal, etc... When they got up to leave they handed their kid the tip money and had him give it to the waitress (he was about 13). As they were walking out the kid goes, here's your tip, and held out the money and gave her 5 bucks. She smiled and graciously accepted and said thanks so much. Our meal was a little over $70 and we didn't have drinks (we are water drinkers) or dessert . They had much more food then us, sodas on the table, wine, etc... so their bill must have been at least $100 (guessing). It made me wonder, is it right to go out to eat at a nice restaurant when the servers are expecting a tip as it is their primary source of income? Do most people tip like this even after seeming like they had a great time?

Could you distill the essence of the text into 1-3 sentences?
<bot>: Saw a family have a good time at a restaurant, had a plentiful meal, and only tipped the waitress 5 bucks for a bill around $100.
