16．Potato chips，which are popular everywhere today，had an unusual origin．The snack came about because of a complaint and an argument．An American named George Crum is credited with inventing potato chips．（71）F
In 1853，Crum worked in Saratoga Springs as the chef．One day a customer sent his serving of fried potatoes hack to the chef，complaining that they should have been sliced thinner．Chef Crum prepared another serving of thinner fried potatoes．The customer again returned them．By this time，Crum was angry．He thinly sliced a large number of potatoes and then salted and fried them．（72）GTo Crum's surprise，the customer loved them．The man even requested more．Afterwards，the customer left the restaurant to tell everyone about the delicious new food．
（73）EWhat is known is that Crum named his new dish"potato crunches，"although locally they became known as Saratoga Chips．When Crum opened a new restaurant，he put baskets of his chips on all the tables．Some people claimed，however，that potato crunches were not even on the menu．People who are aware of the success of the potato chip industry think it strange that Crum never patented his Saratoga Chips．
An important advance in the potato chip industry came in 1926，when Laura Scudder developed the waxed paper bag at her potato chip factory．Scudder had her workers take home sheets of waxed paper to make into small bags．The workers used their clothing irons to iron the sheets of paper．The heat from the irons quickly melted the wax，causing the sheets of paper to stick together．（74）CThe tops were then sealed with heated irons．The hags kept the chips fresher so they could be shipped to customers far away．
Three years later，a new type of fryer allowed further development in the cooking of potato chips．With the continuous fryer，many more chips could be cooked at the same time．Today，people all over the country enjoy the tasty snack．（75）B
