I've had the same customer email me 5 times in an hour, what a dimwit.
First he couldn't open attachments in an adobe document by clicking on the picture of the document.
Then he had idiot questions on taxable items. "You pay taxes on parts. it's not part of the service call."
I emailed him the attachments on a silver platter and now he wants to know why some fields are empty. He's like a beaver trying to plug holes.
Just because they are there doesn't mean I have to fill them in, it's not relevant.
He wanted me to go back and mark things N/A in all the boxes, told him to do it himself.
