Eurpeans in the book

From the text;

(Europeans, no doubt spoiled by their trade union-ridden, high-wage welfare states, generally do not know that they are supposed to tip. Some restaurants, the Hearthside included, allow servers to "grat" their foreign customers, or add a tip to the bill. Since this amount is added before the customers have a chance to tip or not tip, the practice amounts to an automatic penalty for imperfect English.)
