Inviting for cup of coffee
A: John! Wait a second! I was just heading downstairs for a cup of coffee. You want to come? I’ve got some good news!
B: Sure. Let me just grab my wallet. You certainly do look happy this morning.
A: I am. Don’t worry about getting your wallet. It’s my treat.
B: This is a first! You must have won the lottery.
