When receiving service, such as at a hotel, dining out, etc. what do you consider ”good service” worthy of a generous tip?

Based off this question and some of the responses, it had me wondering what great ”tip worthy” service looked like? I am sure each has their own criterion; their coffee cup never ran dry, they were always asked if they needed anything more; a box, napkins, more condiments, etc. if they were brought extra pillows or blankets, there was plenty of towels, and soap, etc. Some think some of the aforementioned acts are a normal and expected part of the person’s job, others see it as an added extra or effort worthy of notice and monetary compensation. What does good service look like to you that will have you gladly loosen your wallet?
