A lot of nicer restaurants include the tip AND leave another tip line so the waiter/waitress will get 15% that's already figured in plus an additional tip that an unknowing customer will add. If you go to Longhorn Steakhouse check your bill before adding the tip - a 15% tip will already be on the bill and is included in the total.
My guess would be this is the case in this situation and the server is making it look like the 'single mom' didn't leave a tip at all. Since we can't see the entire bill I'm going with the tip was built into the bill and mom chose not to leave an additional one.
Sorry if this was already mentioned in the thread.
