The guest did not like those, either. That make 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 also liked them. So, Mr. Crum’s potato chips were added to the menu. They called Saratoga Chips.
