The Olive Garden Targets Tap Water & Wins! A certain sister of mine works for an OG, so I get the inside scoop on how they try to manipulate customers into spending more money on things they don't want. Well, manipulate is too strong a word, since it never seems to be anything clever, just instructing their waitstaff to push customers towards desserts or sodas. Often these instructions involve internal sales contests as employee "incentive", so it's more like manipulation of the waitstaff to push on the customers.
It's particularly delightful that this article is an industry article (from Coca-Cola) praising the practice:
When the contest was completed, almost all participating restaurants realized significant increases in beverage sales and reduced levels of tap water incidence - a strong indication that Olive Garden restaurants succeeded in enhancing the customer's dining experience.
The MetaFilter thread on this is entertaining.
Coca Cola has removed the web site, but the New York Times noticed in time and wrote up the story.
