You might be thinking of anchoring. Some restaurants have a couple of outrageously expensive wines on top of the menu for that reason - everything else looks cheaper in comparison, since the first thing you saw is “anchored” in your mind and used as a point of reference.
I forget if there’s a term for it but I think it’s intentional because it raises the expectations for what people think the minimum acceptable tip is.
Is it price anchoring maybe? Seems like I knew the term for it and can’t remember it now, ha ha!
