Ed, a Businessperson, Is a Friend of Fran, the Owner

Essay

Ed, a businessperson, is a friend of Fran, the owner of Good Morning, a coffee pastries kiosk. Every day, Ed spends five minutes at the kiosk, looking at the goods and usually buying one or two cinnamon buns or bagels. One afternoon, Ed looks at the items, and picks up a $1 chocolate brownie. He waves the brownie at Fran without saying a word and walks on. Is there a contract? If so, how would it be classified in terms of formation, performance, and enforceability?
