M: This is Victoria from corporate headquarter. I haven’t received your last month’s expense reports yet, and they were due on Tuesday.
W: Actually they were sent to you on Monday with the company courier. You haven’t received them yet?
M: No, and I will check with the courier’s office. But meanwhile, could you send them again, just to ensure that I have them by this afternoon? I really appreciate it.
W: Sure, I’ll try to get them on the 9 o’clock courier run.
