2 Brynn is a friend of Bianca, the owner of Coffee Culture, a popular coffee shop in Corvallis, Oregon. Every day, Brynn spends 10 minutes at the store, browsing the food and usually buys either a Peanut Butter Fudge Brownie or a Power Up Breakfast Bagel. One morning, Brynn looks at the items, and selects a $1 Butter Croissant. Brynn waves the donut at Bianca without saying a word and leaves the store. Is there a contract? If so, how would you classify this contract in terms of formation, performance, and enforceability
