My Dad called me once and said to expect a call from a friend of his who I barely knew he had a computer question. I said what does so and so do for a living? He said he makes custom window blinds. I said let me go get some measurements because I am sure he makes them for free too. This all started with pagers I remember people would page and add 911 and be ticked if you didn't call back immediately. I am not going to leave a meeting with one customer or person who had the courtesy to set up an appointment to meet with you just because you typed 911 on your page.
