Albert and Luis, lifelong friends, had a tradition. Every Friday, they took turns going to the corner store and buying what they called a “package”—some vodka and a lottery ticket. One lucky Friday, Albert purchased the package, but Luis scratched off the lottery ticket, only to learn that it was a $20,000 winner. Luis refused to share. Albert sued, claiming the former friends had an enforceable contract supported by valid consideration. Rule on the case.
