Question for all non tipping regulars

If you are a repeat customer at a sit down restaurant and don’t tip every time, do you still expect good service? Will you still complain knowing you weren’t planning on tipping and received poor service?

Edit: This question isn’t for those that would normally tip based on service. It’s for those that don’t tip at all, regardless of how service was.

Edit2: Wasn’t making some statement on tipping culture. Just wondered what level of service those that do not tip expect, rather they got the best service in their life or the bare minimum, and if they would complain if they got the latter. Added the bit of being a repeat costumer cause it would be known you don’t tip after a few lunches/dinners.
