Scheduling a medical appointment

Scheduling medical appointments is difficult.
If you get one detail wrong you are likely to get everything screwed up.
You can be on the phone with them and say, Hello, my name is John I’ve talked to you every day since last Friday, this is Rudy right? I’m still trying to get that appointment for next Monday the 30th at the office in San Francisco. Excuse me, I misspoke, the 30th is a Tuesday.
Okay, no problem, Rudy says, I can schedule you now.
Great you say, I’ve been calling you about this appointment since last week, great, I am glad to get this taken care of.
No problem, I’m scheduling you for your appointment Tuesday the 30th in Egypt.
In Egypt?? you say.
Yes, in Cairo– Oh, I’m sorry I thought you said Monday, Rudy says.
You’ll have to call back tomorrow.
