When you do an upgrade to the internet connection. Don't tell anybody, just sit smiling sweetly to yourself that you know it is going faster.
If you make a grand annoucement about this upgrade, you will be bombarded with queries that start with; "Since the internet connection was upgraded......"
eg. "Since the Internet connection was upgraded, my machine runs a lot slower"
No matter how many times you point it out, create elaborate signs about it, bollock them, report them to their line manager for being timewasting lackwits in need of training, or just ignore them and let them quietly self-destruct, no-one uses the help menu, presses F1 or rtfm.
