Dear website client,

I'm sorry I got snippy with you on the phone. I felt bad about that for the rest of the day. But I have to say...My time is as valuable as yours, and I know you were lying when you told me that you followed the written directions and that you still got an error message. It's obvious that you never even looked at them. I'm not stupid. I strongly suspect that you are, but I still shouldn't have let me tone of voice betray that suspicion. Next time I will be nothing but cool and professional...as I imagine banging my head against a wall.

Thank you.
