How are you doing today?
I'm fine.
What can I do for you?
I would like to cancel a check.
Is there a problem?
I wrote the check out for too much.
How much did you write it out for?
I wrote it out for $ 150.
How much was it supposed to be?
It was supposed to be for $ 100.
I'll cancel that check for you.
I really appreciate your help.
