My parents always told me that if you intend to tip less or not at all then you have an issue worthy of management, if it&#x27;s not worthy of management, then proceed normally even if not completely thrilled with the staff. Their logic being the tip is part of their pay, if you&#x27;re docking their pay, it must be severe and management should be involved.<p>So, I&#x27;ve tipped 20 percent to mediocre waitstaff plenty.<p>I also have this bleeding heart issue where I feel like maybe I was there on their bad day and I tip well because I&#x27;ve had those days :)
