Why is the pay rate of the waiters vis-a-vis the kitchen staff of any concern at all to you? And what makes you think you have any sense of the labor market for wait and kitchen staff? Do you fret over pay disparity in other retail interactions? Honestly it seems more like a post-hoc justification to avoid an interaction which seems to make many people uncomfortable. There is tension between not wanting to feel like a chump for voluntarily overpaying and not not wanting to appear cheap.
