Uke ran an ad in the local newspaper that read: "Want to learn how to play the ukulele?One-on-one lessons for just $60/hour!Special this month:Free lei with first email."

Sarah saw the ad and wrote an email to Uke reading:"I would like to sign up for a ukulele lesson.Can we meet next Tuesday at 10 am, in Luna Beach?"

Uke replied to Sarah, "Thanks for your interest!That's a long drive for me; can we meet at the Wayland Beach pier?"

Sarah replied:"That would be great!I work right across the street, so I can meet you before I start my shift.See you Tuesday at 10 at the WB pier!"

Uke replied:"Super.I might be a little late; WB traffic can get pretty thick on weekday mornings."

Sarah showed up at the Wayland Beach pier at 10 am on Tuesday morning.She waited for 15 minutes before Uke showed up."Sorry I'm late," he said, "but I was tied up trying to find a lei.The flower shop where I usually buy leis was all out and nobody else had one."

Sarah, exasperated, said, "OK, but I can only take a 45-minute lesson.I have to stop at 11 so I can get to work on time.Here's a check for $45same as the $1/minute you charge for an hour's lesson."

Uke didn't take the check."Uh, sorry, but I have to charge $60 to cover my gas.And I don't take personal checkscash, only, please."

Sarah didn't have any cash, didn't want to pay $60, and was annoyed about Uke showing up late and without a lei.The two fell to arguing and parted without exchanging lessons or money.Setting aside the silliness of suing over so trivial a dispute, describe the rights and remedies of the parties under contract law
