Excited Paul and Max get to the BeerCraftery brewery's 3rd anniversary party.
At the entrance, an employee greets them: Welcome to BeerCraftery! Buy an anniversary glass and get a free drink ticket!
Max: I thought there would be free beer.
Employee: Yes. You buy (and keep) a glass and it comes with one free fill.
Max whines: Laaame! Who does a birthday party with only one free beer?!
Employee whines: Laaame! Who comes to a birthday party without a gift?!
Max: If I pick some flowers next to the road, can I get the pitcher?
