阅读下面的短文，根据短文内容完成表格。

An American named Crum invented potato chips in 1853, although that was not his intention(意图). He was a chef(厨师长) at a beautiful restaurant in Saratoga Springs, New York. A regular dish on the menu was fried(油炸的) potatoes, which was an ides that had started in France. At that time, French fried potatoes were cut into thick slices(片).

One day, a dinner guest at the restaurant sent back his fried potatoes to the chef because he did not like them so thick. So Mr Crum cut the potatoes a little thinner and fried them. The guest did not like those either. That made Mr Crum angry, so he thought he would just show the man. He sliced the potatoes paper-thin and fried them, thinking that the man would say nothing about it. However, to his surprise, the man loved the thin potatoes very much. Other guests tried them and liked them. So, Mr Crum’s potato chips were added to the menu. They were called Saratoga Chips.

Finally, Mr Crum opened his own restaurant to sell his famous chips. Now potato chips are packaged(包装) and sold in stores.
