Does that rhyme?
The title of this post is from a blog I (and anyone who works in education would probably) enjoy: The Angry Technician. So here is my first version.
YOUR mobile bill is sent to YOUR department for payment and a copy is sent to YOU for YOUR records (and to look for any personal calls YOU are willing to admit to). So why ask me to go through all YOUR bills and work out YOUR average data usage? I don’t have YOUR bills, I have to get them from Vodafone. Why am I YOUR calculator? YOU should have them, do it yourself.
This isn't a technical support request. It is you being lazy.
