I never tip, unless i received exceptional service.

Then again i only eat out at venues where I pay up front or self serve, or in places so posch - I actually WANT to tip the staff for providing an outstanding experience.

On the rare occation I am in a venue where tipping is expected and service and experience are not phenomenal I do not tip and happily send any staff to fuck right off if approached - that sort of establishment SHOULD go under.

So… Umm, where is the actual research paper? I could not find any links to an actual study anywhere on the project site?

You see, when the US pisses on the rest of the world, the rest of the world gets wet - But when the rest of the world will piss on the US, the US will drown.
