Dear Andrew hall,
Following on from the restaurant meal that you provided us with last night, I have a enquiry to make about the total invoice. Your invoice clearly shows that the meal for twenty of us has been charged at $750 and is therefore missing the $50 discount that had been agreed upon. As this invoice is going to be submitted to the finance department, I do require a bill showing the correct amount. As such before I can submit the check to yourself I will need a correct invoice. I look forward to your earliest response.
Sincerely,
Jonathon
