Study shows French men tip blondes better PARIS, April 21 (UPI) -- A new survey says it pays to be a blonde when waiting tables in France because flaxen-haired waitresses rake in bigger tips. A University of Brittany-South polled male diners and found that tips given to blond waitresses are generally 25 percent larger than the ones left for their brunette colleagues. Nicolas Guegen told the local.fr that his project involved putting different-color wigs on the same servers so that the level of service would not vary. At the same time, female diners were consistent in their gratuities regardless of their waitresses' locks.
