A Surprise Birthday Party for Mike

I decided to have a surprise birthday party for Mike. We told Mike that Lee (our other guitar player) wanted to have a surprise party for his Aunt and Uncle’s anniversary. So we got together and practiced a few times over a couple months. Mike asked Lee if it would be ok to invite his children and Lee said it would be ok, but there would be crab legs there and he was not sure how much that would cost. So Mike hands Lee a check for $100 to cover the crab legs for his family. That night after we had just finished a song, Lee got on the mic and told the story and announced that he was giving the $100 check back to Mike…
