This reminds me a lot of a previous HN post (Observations from a Tipless Restaurant): https://news.ycombinator.com/item?id=6126926 https://news.ycombinator.com/item?id=6126926 They observed that serving staff who were thinking about the tips they would be getting fared worse in their service as the servers would not be able to concentrate as well on the orders that they were taking.
