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.

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

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.
