How are you?
I'm doing well.
How may I help you?
Could you cancel a check for me?
What's the problem?
I wrote the check out for way too much.
How much?
I wrote the check out for $ 150.
What were you supposed to write it out for?
I was supposed to write the check out for $ 100.
I'll just cancel it for you right now.
That's great. You're a lifesaver.
