Need to vent!

Happens to me all the time. Just the other day I fixed up a lawnmower for a friend, new air filter, carb kit, plug, sharpened blade, and oil change... worked with the guy for 7 years now. I used him for a reference for a new job, he says oh yea they called, but I don't have time to call them back. People are dicks for the most part, and I personally won't go out of my way for others anymore.
