If I tip, which will always be discretionary, I will do it in cash. I have never, and will never, used the space on the bill, or in app. I want my tip to go to the person who provided the excellent service alone, not to be shared with their employer or every other server in the restaurant. Providing a line item for tips probably reduces my chances of tipping at all.
