I'm a software dev so naturally I do systems admin too
Yesterday I sent an email out - "You computer may show a little red shield in the bottom, right corner of the screen warning you about security problems - please ignore it as we are upgrading our anti-virus programs. The shield should disappear after a few moments.
I am imposing a charge of £5 for everyone who asks me about this and has been sent this email."
Well, yesterday I would have made about £75 out of this charge.
